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 Splunk APIs

You must specify the URL to a valid Splunk server. By default the driver makes requests on port 8089.

By default, the driver attempts to negotiate TLS/SSL with the server. For more information on TLS/SSL configuration, see SSL Configuration.

Authenticating to Splunk

There are two ways to authenticate to Splunk data: logging in with Splunk credentials, or using a Splunk authentication token.

Splunk Credentials

To authenticate with Splunk credentials, set User and Password to your login credentials.

Splunk Token

When you access Splunk via an authentication token, you can access the Splunk platform using Representational State Transfer (REST) calls. On Splunk Enterprise, you can also use the CLI. Both of these methods enable you to access the instance and make requests without having to authenticate via credentials.

Note: Unless you are accessing a search head cluster (where you can use the same token to access all available head clusters), you must have a separate token for each instance being accessed.

To authenticate with a Splunk token:

1. In the Splunk UI, navigate to Users and Authentication > Tokens to access your assigned authentication token. If you do not have one, request one from the administrator of the instance you want to access.
2. Set the AuthScheme to AccessToken; and the AccessToken property to your Splunk token.
