Description

This pull request introduces support for Azure Service Principal M2M (SP) authentication to the PySQL Connector

Key Changes

  • AzureServicePrincipalCredentialProvider, this is the provider that will deal with getting the creds using the azure credentials
  • ClientCredentialsTokenSource, is responsible for managing the token lifecycle for the flow where credentials are obtained using the grant_type: client_credentials
  • Introduced a common HTTP client called DatabricksHttpClient that can be used to unify the Http logic across the connector, to ensure standard client level behaviour

New dependencies

  • Introduced library PyJWT which is required for handling JWT parsing functionalities

Tests

Expanded unit tests to cover:

  • AzureServicePrincipalCredentialProvider.
  • ClientCredentialsTokenSource

Manual Testing

  • Tested the Azure M2M SP flow by creating a SP using Azure Entra ID and then mapping it to a workspace SP. Further queries were made to the workspace using the Azure Entra ID credentials to test it on Databricks Workspace
