PasswordThe password for the distinguished name of the specified user.
UseSSLWhether or not to use SSL to connect to the server.
BaseDNThe base portion of the distinguished name, used for limiting results to specific subtrees.
AuthMechanismThe authentication mechanism to be used when connecting to the Active Directory server.
ScopeWhether to limit the scope of the search to the whole subtree (BaseDN and all of its descendants), a single level (BaseDN and its direct descendants), or the base object (BaseDN only).
UseDefaultDCUsed to connect to the default Domain Controller and authenticate using the current user credentials.
IntegratedSecurityWhether or not to use the user's current context when logging in.
LDAPVersionThe LDAP version used to connect to and communicate with the server.

SSL

SSLServerCertSpecifies the certificate to be accepted from the server when connecting using TLS/SSL.

Firewall


PropertyDescription
FirewallTypeSpecifies the protocol the provider uses to tunnel traffic through a proxy-based firewall.
FirewallServerIdentifies the IP address, DNS name, or host name of a proxy used to traverse a firewall and relay user queries to network resources.
FirewallPortSpecifies the TCP port to be used for a proxy-based firewall.
FirewallUserIdentifies the user ID of the account authenticating to a proxy-based firewall.
FirewallPasswordSpecifies the password of the user account authenticating to a proxy-based firewall.

Logging


PropertyDescription
LogfileSpecifes the file path to the log file where the provider records its activities, such as authentication, query execution, and connection details.
VerbositySpecifies the verbosity level of the log file, which controls the amount of detail logged. Supported values range from 1 to 5.
LogModulesSpecifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged.
MaxLogFileSizeSpecifies the maximum size of a single log file in bytes. For example, '10 MB'. When the file reaches the limit, the provider creates a new log file with the date and time appended to the name.
MaxLogFileCountSpecifies the maximum number of log files the provider retains. When the limit is reached, the oldest log file is deleted to make space for a new one.

Schema


PropertyDescription
LocationSpecifies 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.
BrowsableSchemasOptional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC .
TablesOptional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC .
ViewsOptional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC .

Caching


PropertyDescription
AutoCacheSpecifies whether the content of tables targeted by SELECT queries is automatically cached to the specified cache database.
CacheProviderThe namespace of an ADO.NET provider. The specified provider is used as the target database for all caching operations.
CacheConnectionSpecifies the connection string for the specified cache database.
CacheLocationSpecifies the path to the cache when caching to a file.
CacheToleranceNotes the tolerance, in seconds, for stale data in the specified cache database. Requires AutoCache to be set to True.
OfflineGets the data from the specified cache database instead of live Microsoft Active Directory data.
CacheMetadataDetermines whether the provider caches table metadata to a file-based cache database.

Miscellaneous


PropertyDescription
BatchSizeSpecifies the maximum number of rows included in each batch submitted during batch operations. To submit the entire batch as a single request, set BatchSize to 0 .
ConnectionLifeTimeSpecifies the maximum lifetime of a connection in seconds. When the specified time elapses, the provider closes the connection.
FollowReferralsWhether or not to follow referrals returned by the Active Directory server.
FriendlyGUIDWhether to return GUID attribute values in a human readable format.
FriendlySIDWhether to return SID attribute values in a human readable format.
MaxRowsSpecifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY.
OtherSpecifies additional hidden properties for specific use cases., to be used only when our Support team advises it, to address specific issues. See Remarks for details.
PoolIdleTimeoutSpecifies the maximum idle time, in seconds, that a connection can remain in the pool before being closed. Requires UseConnectionPooling=True.
PoolMaxSizeSpecifies the maximum number of connections allowed in the connection pool.
PoolMinSizeSpecifies the minimum number of connections to be maintained in the connection pool at all times.
PoolWaitTimeSpecifies the maximum number of seconds a connection request waits for an available connection in the pool. If the wait exceeds this time, an error is returned.
PseudoColumnsSpecifies the pseudocolumns to expose as table columns, expressed as a string in the format 'TableName=ColumnName;TableName=ColumnName'.
ReadonlyToggles read-only access to Microsoft Active Directory from the provider.
RTKSpecifies the runtime key for licensing the provider. If unset or invalid, the provider defaults to the standard licensing method. This property is only required in environments where the standard licensing method is unsupported or requires a runtime key.
TimeoutSpecifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error.
UseConnectionPoolingEnables the connection pooling feature, which allows the provider to reuse existing connections instead of creating new ones for each request.
UserDefinedViewsSpecifies a filepath to a JSON configuration file that defines custom views. The provider automatically detects and uses the views specified in this file.
