This section describes how to edit the DSN configuration and then authenticate and connect to Suadeo APIs.

DSN Configuration

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the installation process creates a both a user DSN and a system DSN, as described in Installing the Connector.

Note: The connector stores connection information in the Windows registry. To ensure that the connector can write to the registry, either run Power BI as an administrator or use a User DSN for your connection instead of a System DSN.

User DSN

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 Power BI Desktop installation (32-bit or 64-bit).
3. Select the system data source and click Configure.
4. Edit the information on the Connection tab and click OK.

System DSN

Configure the system DSN the same way as the user DSN, except you will need to switch to the System DSN tab before performing Step 3.

If you're using Power BI's On-Premises Data Gateway with Standard mode, you must use the system DSN.

You must also specify a valid location for OAuthSettingsLocation (a path where OAuth credentials are locally stored to avoid repeated OAuth prompts).

This is because the Standard mode runs on service mode and can only access permitted locations, such as C:\Windows\ServiceProfiles\PBIEgwService\AppData\Local\Microsoft\On-premises data gateway.

Connecting to Suadeo

The connector uses the OAuth 2.0 Resource Owner Password Credentials (ROPC) grant for authentication. This method allows you to authenticate with Suadeo using your username and password to obtain an access token.

How Authentication Works

When you connect, the connector automatically:

1. Sends your username and password to the Suadeo OAuth token endpoint
2. Receives an access token in response
3. Uses the access token to authenticate all subsequent API requests
4. Automatically obtains a new access token when needed during the session

Note: Unlike some OAuth implementations, Suadeo does not use a browser-based authorization flow or refresh tokens. Authentication occurs directly using your credentials, and the access token is active only for the duration of the connection session.

Required Connection Properties

To connect to Suadeo, you must set the following properties:

• URL: The base URL of your Suadeo instance.
• User: Your Suadeo username.
• Password: Your Suadeo password.
• AuthenticationName: The name identifier for the authentication configuration in your Suadeo instance. Different authentication names can be configured for different environments or use cases.

Note: The Schema connection property is not required to connect to Suadeo.
