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 Dynamics GP

To connect set URL to the Web services endpoint; for example, http://{servername}:{port}/Dynamics/GPService. Additionally, set CompanyId to the unique identifier of the company you are connecting to. You can obtain this value by querying the Company table and leaving the property empty.

Authenticating to Microsoft Dynamics GP

The Microsoft Dynamics GP data source supports the following authentication methods:

• Anonymous Authentication
• WS-Security (WSS) Authentication
• Basic Authentication
• NTLM User Authentication
• Digest
• Negotiate (Kerberos)

Anonymous Authentication

In some situations, you can connect to Microsoft Dynamics GP without setting any authentication connection properties. To do so, set the AuthScheme to None, and you are ready to connect.

WS-Security (WSS)

Set the User and Password to connect and set AuthScheme to WSS.

Note: WSS Authentication is the default authentication scheme.

Basic

Set the User and Password to connect and set AuthScheme to Basic.

Windows (NTLM)

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

Digest

Set the User and Password to connect and set AuthScheme to Digest.

Kerberos

See Using Kerberos for details on how to authenticate with Kerberos.

Fine Tuning Data Access

The driver returns data summaries by default to save performance. Set LookupIds to true to return details such as line items; however, note that entities must be retrieved one at a time.
