The CData Sync App provides a straightforward way to continuously pipeline your LDAP data to any database, data lake, or data warehouse, making it easily available for Analytics, Reporting, AI, and Machine Learning.
The LDAP connector can be used from the CData Sync application to pull data from LDAP and move it to any of the supported destinations.
The Sync App models LDAP 2 and 3 objects as bidirectional tables. The Sync App is a standard LDAP client as specified in RFC 1777, 2251, and other LDAP RFCs.
For required properties, see the Settings tab.
For connection properties that are not typically required, see the Advanced tab.
The CData driver for the LDAP supports connecting to LDAP server objects. To connect, set the required properties.
Optional properties can be used to further refine control of the returned results.
To authenticate requests, set the User and Password properties to valid LDAP credentials. For example: set User to Domain\\BobF or cn=Bob F,ou=Employees,dc=Domain.
The AuthMechanism properties for the Sync App are as follows:
By default, the driver uses plaintext when communicating with the server set to port=389. The driver automatically switches to use SSL when talking to the LDAP on port=636. You can force the connection to use the SSL connection property when set to SSL=TRUE.
The Sync App surfaces the columns most often needed from LDAP entities. However, if you need to work with other data, the tables are easy to modify. Tables are defined in schema files, which have a simple format.
See Working with LDAP Tables for a guide to extending the default schemas or writing your own. To use custom schemas, set the Location property to the folder containing the schema files. For more on tables and views, see Data Model.
The Sync App includes table schemas for many standard LDAP objects. You can easily extend the included table schemas to edit column behavior or you can write your own from scratch.
Table schemas are defined in .rsd files, which are simple configuration files. This section will walk through different parts of the schema, adding several columns to the Person table as an example.
You can find the Person.rsd file in the db subfolder in the installation folder of the CData Sync App.
To use custom schemas, set the Location property to the folder containing the schema files.
It is important to define a new table with the same name as the object class that the table will represent. This will allow the Sync App to search for only the desired object class when querying the LDAP server. The file name defines the table name.
There are a few columns that every table should include, regardless of the object class:
<rsb:script xmlns:rsb="http://www.rssbus.com/ns/rsbscript/2">
<rsb:info title="Person" description="Create, update, delete, and query person entries in Active Directory.">
<!-- Required Columns -->
<attr name="Id" xs:type="string" readonly="true" key="true" />
<attr name="DN" xs:type="string" readonly="true" required="false" other:ldaptype="OID" />
<attr name="RDN" xs:type="string" readonly="true" required="false" other:ldaptype="Directory String" />
<attr name="BaseDN" xs:type="string" readonly="true" required="false" other:ldaptype="OID" />
Note: The title attribute of the rsb:info block must match the name of the .rsd file.
Each column requires at least name and xs:type attributes. Additionally, you will need to specify dataFormat to decide how data is returned from the table. For example:
<!-- Person Required Attributes -->
<attr name="ObjectClass" other:dataFormat="splitDataByRow" xs:type="string" readonly="false" required="false" other:ldaptype="OID" />
<attr name="SN" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="Directory String" />
<attr name="CN" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="Directory String" />
<!-- Person Optional Attributes -->
<attr name="UserPassword" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="Binary" />
<attr name="TelephoneNumber" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="Directory String" />
<attr name="SeeAlso" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="DN" />
<attr name="Description_1" other:dataFormat="splitDataByCol" xs:type="string" readonly="false" required="false" other:ldaptype="Directory String" />
<attr name="Description_2" other:dataFormat="splitDataByCol" xs:type="string" readonly="false" required="false" other:ldaptype="Directory String" />
<attr name="Description_3" other:dataFormat="splitDataByCol" xs:type="string" readonly="false" required="false" other:ldaptype="Directory String" />
The other:dataFormat attribute has three options:
delimitedData: Return multiple LDAP attribute values as delimited strings, separated by the delimiter character defined in the Table Settings section of the .rsd file, detailed later.
This is the default format in which to retrieve data and the delimiter defaults to a semicolon.
The code below can be used to split the different values of the ObjectClass attributes into their own rows and Description attributes into their own columns. Notice the column definition now includes multiple columns for the Description attribute. Also note the other:dataFormat attribute for the attr.
...
<attr name="ObjectClass" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="OID" />
<attr name="SN" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="Directory String" />
<attr name="CN" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="Directory String" />
<attr name="UserPassword" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="Binary" />
<attr name="TelephoneNumber" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="Directory String" />
<attr name="SeeAlso" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="DN" />
<attr name="Description_1" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="Directory String" />
<attr name="Description_2" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="Directory String" />
<attr name="Description_3" other:dataFormat="delimitedData" xs:type="string" readonly="false" required="false" other:ldaptype="Directory String" />
</rsb:info>
<!-- Table Settings -->
<rsb:set attr="delimiter" value=";"/>
...
An example result will look like:
| Id | DN | ObjectClass | SN | CN | UserPassword | TelephoneNumber | SeeAlso | Description_1 | Description_2 | Description_3 |
| 1|CN=User1,DC=Test | CN=User1,DC=Test | Top | TestSN | User1 | 555-5555 | A;B;C | Desc1 | Desc2 | Desc3 | |
| 2|CN=User1,DC=Test | CN=User1,DC=Test | User | TestSN | User1 | 555-5555 | A;B;C | Desc1 | Desc2 | Desc3 |
In addition to data format on inputs, encoding can also be specified. Currently, returning data with UTF8 encoding or BASE64 encoding is supported. In order to retrieve data with a specified encoding, the other:encoding field must be specified for the desired attribute to be encoded. If no encoding is specified, UTF8 is the default.
An example of specifying encoding for an attribute:
...
<attr name="ObjectClass" other:dataFormat="delimitedData" other:encoding="UTF8" xs:type="string" readonly="false" required="false" other:ldaptype="OID" desc="The object class of the entry."/>
<attr name="SN" other:dataFormat="delimitedData" other:encoding="BASE64" xs:type="string" readonly="false" required="false" other:ldaptype="Directory String" desc="The surname of the person."/>
...
Optionally, there are two attributes that can be used to control how filtering is handled. The other:ldaptype attribute can be used to set the LDAP syntax of a field. This is used to determine the comparison operators that are supported server-side on a per-field basis. For example, if a field is marked as the type 'DN' and a query filtering for a substring (i.e., CONTAINS), which is not supported server-side, the driver will instead process this part of the filter entirely client-side. The supported type names are found in section 4.3.2 of RFC 2252. If you are unsure of the type or just want to disable server-side filtering for a given column entirely, the other:filterable attribute is also available. Setting this to false for the field will prevent this from ever being sent to the server in a filter, overriding the other:ldaptype attribute entirely.
In addition to the attributes and inputs, you will need to specify the delimiter.
The delimiter specifies the character that will be used for delimited data. Delimited data will be returned for any attribute that appears multiple times for a single object (unless otherwise specified in other:dataFormat).
For example, the code below will concatenate multiple values of an attribute using the ';' character.
...
</rsb:info>
<!-- Table Settings -->
<rsb:set attr="delimiter" value=";"/>
...
Operation definitions will remain exactly the same for all newly created tables: Simply copy and paste these from an existing table, as needed.
<!-- Operation definitions -->

This section details a selection of advanced features of the LDAP Sync App.
The Sync App supports the use of user defined views, virtual tables whose contents are decided by a pre-configured user defined query. These views are useful when you cannot directly control queries being issued to the drivers. For an overview of creating and configuring custom views, see User Defined Views .
Use SSL Configuration to adjust how Sync App handles TLS/SSL certificate negotiations. You can choose from various certificate formats;. For further information, see the SSLServerCert property under "Connection String Options" .
Configure the Sync App for compliance with Firewall and Proxy, including Windows proxies. You can also set up tunnel connections.
For further information, see Query Processing.
To enable TLS, set the following:
With this configuration, the Sync App attempts to negotiate TLS with the server. The server certificate is validated against the default system trusted certificate store. You can override how the certificate gets validated using the SSLServerCert connection property.
To specify another certificate, see the SSLServerCert connection property.
Set the following properties:
The CData Sync App models LDAP data as an easy-to-use SQL database. It also includes Stored Procedures that extend the functionality of the Sync App.
The included Tables cover many standard object classes, which define the structure and rules for LDAP directory entries. You can easily extend the table schemas to map more closely to your LDAP classes by modifying simple configuration files. See Working with LDAP Tables for a guide to customizing table schemas.
Note: To use custom tables and schemas, set the Location property to the folder containing the schema files.
The following tables are shipped with the Sync App.

The sche.
Specifies the domain name or IP address of the LDAP server. This property is required to establish a connection and does not need to include the LDAP:\\\\ prefix, only the server’s domain name or IP address.
This property defines the LDAP server's location and must be set to either a domain name like "ldap.example.com" or an IP address such as 192.168.1.1. Do not include the LDAP:\\ prefix, as the provider handles it automatically.
Specifies the port number on which the LDAP server is running.
This property defines the port the LDAP server is running on. By default, it is set to 389, which is the standard port for LDAP. Together with the Server property, this property determines the full connection endpoint. If your LDAP server is configured to use a non-standard port, update this property accordingly.
Specifies the distinguished name (DN) of the user account to be used for authentication with the LDAP server. This property is required when the server enforces authentication.
This property is used, along with the Password property, to authenticate against the LDAP server. The value must be the full distinguished name (DN) of the user account, such as "CN=John Doe,OU=Users,DC=example,DC=com". Ensure the value matches the DN format expected by the LDAP server to avoid authentication failures.
Specifies the password associated with the distinguished name (DN) of the user account used for authentication with the LDAP server. This property is required when the server enforces authentication.
This property is used in conjunction with the User property to authenticate against the LDAP server. Ensure the password corresponds to the specified distinguished name (DN) to avoid authentication failures. For enhanced security, ensure the password is not hardcoded in configuration files. Instead, use environment variables or secure credential storage to handle sensitive values when configuring LDAP authentication.
Specifies the base portion of the distinguished name (DN) to limit LDAP queries to a specific subtree within the directory. Using a base DN helps narrow the search scope and improve query performance, especially on large LDAP servers.
This property sets the starting point for LDAP searches by specifying the base DN. By limiting the search to a specific subtree, the number of entries examined is significantly reduced, which can greatly improve performance on large servers. The value should be a valid DN, such as "DC=example,DC=com", that represents the desired subtree. If left blank, the search scope is not restricted and applies to the entire directory.
Specifies whether SSL is used to secure the connection to the LDAP server. Enabling this property ensures that communication between the client and server is encrypted.
This property specifies whether the connection to the LDAP server should be encrypted using SSL. If set to true, SSL is used to secure the connection. By default, this property is set to false, meaning SSL is not enforced.
However, note the following about LDAP standard ports:
If the Sync App connects to an encrypted endpoint, SSL is automatically used regardless of the value of this property. Ensure that your LDAP server supports SSL if you enable this property.
Specifies the version of the LDAP protocol to use when connecting to the server. The supported values are 2 and 3.
Set this property to specify the LDAP protocol version used for communication. The default value is 2, but many modern LDAP servers require version 3 for compatibility. Ensure that the server you are connecting to supports the specified version to avoid communication errors. The provider complies with LDAP standards as specified in RFC 1777, RFC 2251, and other relevant LDAP RFCs.
Specifies the authentication mechanism to use when connecting to the LDAP server. Supported values are SIMPLE for plaintext authentication and NEGOTIATE for NTLM/Negotiate authentication.
This property specifies the method of authentication to use during connection. The default value is SIMPLE, which uses plaintext credentials to authenticate with the server. If set to NEGOTIATE, NTLM/Negotiate authentication is used, enabling support for Windows-based integrated authentication. Ensure the LDAP server supports the specified authentication mechanism. Use NEGOTIATE for environments that require secure, integrated authentication, while SIMPLE is suitable for scenarios where plaintext credentials are accepted.
Specifies the scope of the LDAP search. This property defines whether the search applies to the entire subtree (BaseDN and all its descendants), a single level (BaseDN and its direct descendants), or just the base object (BaseDN only).
This property is useful for balancing performance and query results. For broad searches that require retrieving entries across the entire directory hierarchy, use WHOLESUBTREE. For more focused queries, select SINGLELEVEL to limit results to the BaseDN’s direct descendants or BASEOBJECT to retrieve only the BaseDN itself. Narrowing the search scope can help reduce unnecessary overhead and improve query efficiency, especially in large directories.
Specifies whether to use distinguishedName or entryDN as the DN attribute in LDAP query filters. This property affects how the distinguished name is referenced during search operations.
This property is useful for specifying how the DN is handled in filters for LDAP queries. The default value is distinguishedName, which is widely used in most LDAP servers. For servers or configurations that rely on entryDN for DN filtering, update this property accordingly. Ensure that the chosen attribute is supported by your LDAP server to avoid query errors.
This section provides a complete list of the SSL properties you can configure in the connection string for this provider.
| Property | Description |
| SSLServerCert | Specifies the certificate to be accepted from the server when connecting using TLS/SSL. |
Specifies the certificate to be accepted from the server when connecting using TLS/SSL.
If you are using a TLS/SSL connection, use this property to specify the TLS/SSL certificate to be accepted from the server. If you specify a value for this property, all other certificates that are not trusted by the machine are rejected.
This property can take the following forms:
| Description | Example |
| A full PEM Certificate (example shortened for brevity) | -----BEGIN CERTIFICATE----- MIIChTCCAe4CAQAwDQYJKoZIhv......Qw== -----END CERTIFICATE----- |
| A path to a local file containing the certificate | C:\cert.cer |
| The public key (example shortened for brevity) | -----BEGIN RSA PUBLIC KEY----- MIGfMA0GCSq......AQAB -----END RSA PUBLIC KEY----- |
| The MD5 Thumbprint (hex values can also be either space- or colon-separated) | ecadbdda5a1529c58a1e9e09828d70e4 |

This section provides a complete list of the Firewall properties you can configure in the connection string for this provider.
| Property | Description |
| FirewallType | Specifies the protocol the provider uses to tunnel traffic through a proxy-based firewall. |
| FirewallServer | Identifies the IP address, DNS name, or host name of a proxy used to traverse a firewall and relay user queries to network resources. |
| FirewallPort | Specifies the TCP port to be used for a proxy-based firewall. |
| FirewallUser | Identifies the user ID of the account authenticating to a proxy-based firewall. |
| FirewallPassword | Specifies the password of the user account authenticating to a proxy-based firewall. |
Specifies the protocol the provider uses to tunnel traffic through a proxy-based firewall.
A proxy-based firewall (or proxy firewall) is a network security device that acts as an intermediary between user requests and the resources they access. The proxy accepts the request of an authenticated user, tunnels through the firewall, and transmits the request to the appropriate server.
Because the proxy evaluates and transfers data backets on behalf of the requesting users, the users never connect directly with the servers, only with the proxy.
The following table provides port number information for each of the supported protocols.
| Protocol | Default Port | Description |
| TUNNEL | 80 | The port where the Sync App opens a connection to LDAP. Traffic flows back and forth via the proxy at this location. |
| SOCKS4 | 1080 | The port where the Sync App opens a connection to LDAP. SOCKS 4 then passes theFirewallUser value to the proxy, which determines whether the connection request should be granted. |
| SOCKS5 | 1080 | The port where the Sync App sends data to LDAP. If the SOCKS 5 proxy requires authentication, set FirewallUser and FirewallPassword to credentials the proxy recognizes. |

This section provides a complete list of the Logging properties you can configure in the connection string for this provider.
| Property | Description |
| LogModules | Specifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged. |
Specifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged.
The Sync App writes details about each operation it performs into the logfile specified by the Logfile connection property.
Each of these logged operations are assigned to a themed category called a module, and each module has a corresponding short code used to labels individual Sync App operations as belonging to that module.
When this connection property is set to a semicolon-separated list of module codes, only operations belonging to the specified modules are written to the logfile. Note that this only affects which operations are logged moving forward and doesn't retroactively alter the existing contents of the logfile. For example: INFO;EXEC;SSL;META;
By default, logged operations from all modules are included.
You can explicitly exclude a module by prefixing it with a "-". For example: -HTTP
To apply filters to submodules, identify them with the syntax <module name>.<submodule name>. For example, the following value causes the Sync App to only log actions belonging to the HTTP module, and further refines it to exclude actions belonging to the Res submodule of the HTTP module: HTTP;-HTTP.Res
Note that the logfile filtering triggered by the Verbosity connection property takes precedence over the filtering imposed by this connection property. This means that operations of a higher verbosity level than the level specified in the Verbosity connection property are not printed in the logfile, even if they belong to one of the modules specified in this connection property.
The available modules and submodules are:
| Module Name | Module Description | Submodules |
| INFO | General Information. Includes the connection string, product version (build number), and initial connection messages. |
|
| EXEC | Query Execution. Includes execution messages for user-written SQL queries, parsed SQL queries, and normalized SQL queries. Success/failure messages for queries and query pages appear here as well. |
|
| HTTP | HTTP protocol messages. Includes HTTP requests/responses (including POST messages), as well as Kerberos related messages. |
|
| WSDL | Messages pertaining to the generation of WSDL/XSD files. | — |
| SSL | SSL certificate messages. |
|
| AUTH | Authentication related failure/success messages. |
|
| SQL | Includes SQL transactions, SQL bulk transfer messages, and SQL result set messages. |
|
| META | Metadata cache and schema messages. |
|
| FUNC | Information related to executing SQL functions. |
|
| TCP | Incoming and outgoing raw bytes on TCP transport layer messages. |
|
| FTP | Messages pertaining to the File Transfer Protocol. |
|
| SFTP | Messages pertaining to the Secure File Transfer Protocol. |
|
| POP | Messages pertaining to data transferred via the Post Office Protocol. |
|
| SMTP | Messages pertaining to data transferred via the Simple Mail Transfer Protocol. |
|
| CORE | Messages relating to various internal product operations not covered by other modules. | — |
| DEMN | Messages related to SQL remoting. | — |
| CLJB | Messages about bulk data uploads (cloud job). |
|
| SRCE | Miscellaneous messages produced by the product that don't belong in any other module. | — |
| TRANCE | Advanced messages concerning low-level product operations. | — |
This section provides a complete list of the Schema properties you can configure in the connection string for this provider.
| Property | Description |
| Location | Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path. |
| BrowsableSchemas | Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC . |
| Tables | Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC . |
| Views | Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC . |
Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.
The Location property is only needed if you want to either customize definitions (for example, change a column name, ignore a column, etc.) or extend the data model with new tables, views, or stored procedures.
If left unspecified, the default location is %APPDATA%\\CData\\LDAP Data Provider\\Schema, where %APPDATA% is set to the user's configuration directory:
| Platform | %APPDATA% |
| Windows | The value of the APPDATA environment variable |
| Linux | ~/.config |
Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC .
Listing all available database schemas can take extra time, thus degrading performance. Providing a list of schemas in the connection string saves time and improves performance.
Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC .
Listing all available tables from some databases can take extra time, thus degrading performance. Providing a list of tables in the connection string saves time and improves performance.
If there are lots of tables available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those tables. To do this, specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.
Note: If you are connecting to a data source with multiple schemas or catalogs, you must specify each table you want to view by its fully qualified name. This avoids ambiguity between tables that may exist in multiple catalogs or schemas.
Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC .
Listing all available views from some databases can take extra time, thus degrading performance. Providing a list of views in the connection string saves time and improves performance.
If there are lots of views available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those views.

For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.
Note: If you are connecting to a data source with multiple schemas or catalogs, you must specify each view you want to examine by its fully qualified name. This avoids ambiguity between views that may exist in multiple catalogs or schemas.
This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.
| Property | Description |
| FollowReferrals | Specifies whether to follow LDAP referrals returned by the LDAP server. When enabled, the provider retrieves data from the referred servers instead of the original server. |
| FriendlyGUID | Specifies whether GUID attributes, such as objectGUID, are returned in a human-readable string format or as base64-encoded binary objects. When enabled, the property converts GUIDs into a friendly string format. |
| FriendlySID | Specifies whether SID attributes, such as objectSid, are returned in a human-readable string format or as base64-encoded binary objects. When enabled, the property converts SIDs into a friendly string format. |
| MaxRows | Specifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY. |
| Other | Specifies advanced connection properties for specialized scenarios. Use this property only under the guidance of our Support team to address specific issues. |
| PseudoColumns | Specifies the pseudocolumns to expose as table columns, expressed as a string in the format 'TableName=ColumnName;TableName=ColumnName'. |
| Timeout | Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. |
| UserDefinedViews | Specifies a filepath to a JSON configuration file that defines custom views. The provider automatically detects and uses the views specified in this file. |
Specifies whether to follow LDAP referrals returned by the LDAP server. When enabled, the provider retrieves data from the referred servers instead of the original server.
This property specifies whether the provider should follow referrals returned by the LDAP server during queries. Referrals are pointers to other LDAP servers that may contain the requested data. When FollowReferrals is set to true, the provider connects to the referral servers to retrieve data. Note that data operations such as INSERT, UPDATE, or DELETE cannot be performed on referral servers unless the connection string is updated to connect directly to those servers.
Specifies whether GUID attributes, such as objectGUID, are returned in a human-readable string format or as base64-encoded binary objects. When enabled, the property converts GUIDs into a friendly string format.
This property specifies how GUID attributes, such as objectGUID, are returned when inspecting object attributes. If set to true, GUIDs are converted into a human-readable string format. If set to false, GUIDs are returned as base64-encoded binary objects. The friendly string format makes GUID values easier to interpret and work with during debugging or when creating readable reports. This property is useful in scenarios where GUIDs need to be reviewed manually or shared in a clear, human-readable format.
Specifies whether SID attributes, such as objectSid, are returned in a human-readable string format or as base64-encoded binary objects. When enabled, the property converts SIDs into a friendly string format.
This property specifies how SID attributes, such as objectSid, are returned when inspecting object attributes. If set to true, SIDs are converted into a human-readable string format. If set to false, SIDs are returned as base64-encoded binary objects. The friendly string format simplifies working with SID values, making them easier to interpret during debugging or when generating reports. This property is useful in scenarios where SIDs need to be reviewed manually or shared in a clear, human-readable format.
Specifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY.
The default value for this property, -1, means that no row limit is enforced unless the query explicitly includes a LIMIT clause. (When a query includes a LIMIT clause, the value specified in the query takes precedence over the MaxRows setting.)
Setting MaxRows to a whole number greater than 0 ensures that queries do not return excessively large result sets by default.
This property is useful for optimizing performance and preventing excessive resource consumption when executing queries that could otherwise return very large datasets.
Specifies advanced connection properties for specialized scenarios. Use this property only under the guidance of our Support team to address specific issues.
This property allows advanced users to configure hidden properties for specialized situations, with the advice of our Support team. These settings are not required for normal use cases but can address unique requirements or provide additional functionality. To define multiple properties, use a semicolon-separated list.
Note: It is strongly recommended to set these properties only when advised by the Support team to address specific scenarios or issues.
| Property | Description |
| DefaultColumnSize | Sets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000. |
| ConvertDateTimeToGMT=True | Converts date-time values to GMT, instead of the local time of the machine. The default value is False (use local time). |
| RecordToFile=filename | Records the underlying socket data transfer to the specified file. |
Specifies the pseudocolumns to expose as table columns, expressed as a string in the format 'TableName=ColumnName;TableName=ColumnName'.
This property allows you to define which pseudocolumns the Sync App exposes as table columns.
To specify individual pseudocolumns, use the following format:
Table1=Column1;Table1=Column2;Table2=Column3
To include all pseudocolumns for all tables use:
*=*
Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error.
The timeout applies to each individual communication with the server rather than the entire query or operation. For example, a query could continue running beyond 60 seconds if each paging call completes within the timeout limit.
Timeout is set to 60 seconds by default. To disable timeouts, set this property to 0.
Disabling the timeout allows operations to run indefinitely until they succeed or fail due to other conditions such as server-side timeouts, network interruptions, or resource limits on the server.
Note: Use this property cautiously to avoid long-running operations that could degrade performance or result in unresponsive behavior.
Specifies a filepath to a JSON configuration file that defines custom views. The provider automatically detects and uses the views specified in this file.
UserDefinedViews allows you to define and manage custom views through a JSON-formatted configuration file called UserDefinedViews.json. These views are automatically recognized by the Sync App and enable you to execute custom SQL queries as if they were standard database views. The JSON file defines each view as a root element with a child element called "query", which contains the SQL query for the view.
For example:
{
"MyView": {
"query": "SELECT * FROM User WHERE MyColumn = 'value'"
},
"MyView2": {
"query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
}
}
You can use this property to define multiple views in a single file and specify the filepath.
For example:
UserDefinedViews=C:\Path\To\UserDefinedViews.jsonWhen you specify a view in UserDefinedViews, the Sync App only sees that view.
For further information, see User Defined Views.

NSIS 3.10
Copyright (C) 1999-2025 Contributors THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS COMMON PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
1. DEFINITIONS
"Contribution" means:
a) in the case of the initial Contributor, the initial code and documentation distributed under this Agreement, and b) in the case of each subsequent Contributor:
i) changes to the Program, and
ii) additions to the Program;
where such changes and/or additions to the Program originate from and are distributed by that particular Contributor. A Contribution 'originates' from a Contributor if it was added to the Program by such Contributor itself or anyone acting on such Contributor's behalf. Contributions do not include additions to the Program which: (i) are separate modules of software distributed in conjunction with the Program under their own license agreement, and (ii) are not derivative works of the Program.
"Contributor" means any person or entity that distributes the Program.
"Licensed Patents " mean patent claims licensable by a Contributor which are necessarily infringed by the use or sale of its Contribution alone or when combined with the Program.
"Program" means the Contributions distributed in accordance with this Agreement.
"Recipient" means anyone who receives the Program under this Agreement, including all Contributors.
2. GRANT OF RIGHTS
a) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, distribute and sublicense the Contribution of such Contributor, if any, and such derivative works, in source code and object code form.
b) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free patent license under Licensed Patents to make, use, sell, offer to sell, import and otherwise transfer the Contribution of such Contributor, if any, in source code and object code form. This patent license shall apply to the combination of the Contribution and the Program if, at the time the Contribution is added by the Contributor, such addition of the Contribution causes such combination to be covered by the Licensed Patents. The patent license shall not apply to any other combinations which include the Contribution. No hardware per se is licensed hereunder.
c) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property rights of any other entity. Each Contributor disclaims any liability to Recipient for claims brought by any other entity based on infringement of intellectual property rights or otherwise. As a condition to exercising the rights and licenses granted hereunder, each Recipient hereby assumes sole responsibility to secure any other intellectual property rights needed, if any. For example, if a third party patent license is required to allow Recipient to distribute the Program, it is Recipient's responsibility to acquire that license before distributing the Program.
d) Each Contributor represents that to its knowledge it has sufficient copyright rights in its Contribution, if any, to grant the copyright license set forth in this Agreement.
3. REQUIREMENTS
A Contributor may choose to distribute the Program in object code form under its own license agreement, provided that:
a) it complies with the terms and conditions of this Agreement; and
b) its license agreement:
i) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and fitness for a particular purpose;
ii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, incidental and consequential damages, such as lost profits;
iii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any other party; and
iv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it in a reasonable manner on or through a medium customarily used for software exchange.
When the Program is made available in source code form:
a) it must be made available under this Agreement; and
b) a copy of this Agreement must be included with each copy of the Program.
Contributors may not remove or alter any copyright notices contained within the Program.
Each Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows subsequent Recipients to identify the originator of the Contribution.
4. COMMERCIAL DISTRIBUTION
Commercial distributors of software may accept certain responsibilities with respect to end users, business partners and the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes the Program in a commercial product offering should do so in a manner which does not create potential liability for other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor ("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may participate in any such claim at its own expense.
For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, the Commercial Contributor must pay those damages.
5. NO WARRANTY
EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely responsible for determining the appropriateness of using and distributing the Program and assumes all risks associated with its exercise of rights under this Agreement, including but not limited to the risks and costs of program errors, compliance with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations.
6. DISCLAIMER OF LIABILITY
EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
7. GENERAL
If any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.
If Recipient institutes patent litigation against a Contributor with respect to a patent applicable to software (including a cross-claim or counterclaim in a lawsuit), then any patent licenses granted by that Contributor to such Recipient under this Agreement shall terminate as of the date such litigation is filed. In addition, if Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such litigation is filed.
All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses granted by Recipient relating to the Program shall continue and survive.
Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the right to modify this Agreement. IBM is the initial Agreement Steward. IBM may assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the Agreement will be given a distinguishing version number. The Program (including Contributions) may always be distributed subject to the version of the Agreement under which it was received. In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or otherwise. All rights in the Program not expressly granted under this Agreement are reserved.
This Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States of America. No party to this Agreement will bring a legal action under this Agreement more than one year after the cause of action arose. Each party waives its rights to a jury trial in any resulting litigation.
