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.

Before You Connect

Before you can establish a connection, you must contact ADP and ask that they provide you with an OAuth app and its associated credentials.

These credentials can only be obtained from ADP and can't be retrieved directly.

Connecting to ADP

Connect to ADP by specifying the following properties:

• OAuthClientId: Set this to the client Id of the app provided by ADP.
• OAuthClientSecret: Set this to the client secret of the app provided by ADP.
• SSLClientCert: Set this to the certificate provided by ADP.
• SSLClientCertPassword: Set this to the password of the certificate.
• UseUAT: The driver makes requests to the production environment by default. If using a developer account, set UseUAT = true.
• RowScanDepth: The maximum number of rows to scan for the custom fields columns available in the table. The default value will be set to 100. Setting a high value may decrease performance.

Note: SSLClientCert requires that you create your own certificate. See ADP Developer Resources for more information.
