Windows DSN Configuration

Using the Microsoft ODBC Data Source Administrator

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the DSN is created during the installation process.

Complete the following steps to edit the DSN configuration:

Select Start > Search, and enter ODBC Data Sources in the Search box.
Choose the version of the ODBC Administrator that corresponds to the bitness of your application (32-bit or 64-bit).
Click the System DSN tab.
Select the system data source and click Configure.
Edit the information on the Connection tab and click OK.

Note: For .NET Framework 4.0, the driver distributes Microsoft Visual C++ 2015-2022 Redistributable. For .NET Framework 3.5, the driver distributes Microsoft Visual C++ 2008 Redistributable.

Ensuring Registry Access

The driver stores connection information in the Windows registry. To ensure that the driver can write to the registry, perform either of the following actions:

Run the calling application as an administrator.
Connect via a User DSN instead of a System DSN.

Connecting to Sybase

To connect to the Sybase, specify the following connection properties:

Server: Set this to the name or network address of the Sybase database instance.
Database: Set this to the name of the Sybase database running on the specified Server.

Optionally, you can also secure your connections with TLS/SSL by setting UseSSL to true.

Authenticating to Sybase

Sybase supports several methods for authentication including Password and Kerberos.

Password

Set the AuthScheme to Password and set the following connection properties to use Sybase authentication.

User: Set this to the username of the authenticating Sybase user.
Password: Set this to the username of the authenticating Sybase user.

Kerberos

To leverage Kerberos authentication, begin by enabling it via the following connection property:

AuthScheme: Set to Kerberos will be used for authentication to Sybase.

See Using Kerberos information regarding the connection properties that need to be set for Kerberos authentication.

You can find an example connection string below:

Server=MyServer;Port=MyPort;User=SampleUser;Password=SamplePassword;Database=MyDB;Kerberos=true;KerberosKDC=MyKDC;KerberosRealm=MYREALM.COM;KerberosSPN=server-name
