Cause

This issue occurs when the logged in user (attempting to configure the data source connection) is unable to authentication against the active directory. 

Action

Any one of the following steps can resolve the issue: 

1. Engage the Microsoft AD team to resolve the authentication issue and ensure that user used to connect to the datasource has the appropriate permissions. 
2. Disable Active Directory Authentication and use MS SQL authentication instead on the Azure Console or on the database server.
