Configure Databricks environment with DBX Service Principal.

[Gordon111]

I know PAT is the preferred auth method for creating a Databricks environment, but my work is moving away from those and will no longer allow developers to generate them.

Is there a way I can authenticate with a Databricks Managed Service Principal instead? Or is this simply not possible?

I am using version 5.4.4

Hi @Gordon111,

Welcome to the Forum!

Yes, you can connect to Databricks using a Service Principal via the OAuth2 Authenticator (Client Credentials) node in KNIME.

In the configuration, fill in the following:

• Token endpoint: https://<your-workspace>.cloud.databricks.com/oidc/v1/token
• ID and Secret (flow variable): Provided via a flow variable from the Credentials Configuration node (Client ID and Secret of your service principal)
• Scope: all-apis

Once configured, connect the OAuth2 Authenticator to the Databricks Workspace Connector, set your workspace URL there, and then continue to the Create Databricks Environment node.

Best,
Keerthan
