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:

1. Select Start > Search, and enter ODBC Data Sources in the Search box.
2. Choose the version of the ODBC Administrator that corresponds to the bitness of your application (32-bit or 64-bit).
3. Click the System DSN tab.
4. Select the system data source and click Configure.
5. 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:

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

Connecting to Microsoft SQL Server Analysis Services

To connect, set the Url property to a valid Microsoft SQL Server Analysis Services endpoint and provide authentication. The driver must connect to Microsoft SQL Server Analysis Services instances hosted over HTTP with XMLA access. See the Microsoft documentation to configure HTTP access to Microsoft SQL Server Analysis Services.

Authenticating to Microsoft SQL Server Analysis Services

The driver supports the major authentication schemes, including HTTP and Windows.

Set AuthScheme to use the following authentication types.

Anonymous Authentication

If anonymous authentication is available, set AuthScheme to none to avoid authentication.

Basic

Set SQL Server database User and Password and set AuthScheme to "BASIC".

Windows (NTLM)

Set the Windows User and Password and set AuthScheme to "NTLM".

Kerberos

Please see Using Kerberos for details on how to authenticate with Kerberos.

Securing Microsoft SQL Server Analysis Services Connections

By default, the driver attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats.
