When running the connectivity tests through GUI, the test runs successfully. But on executing with the FlexiBRSVC, an authentication failure message is received.
This error was caused by a bug in the ODBC driver which was related to Azure AD authentication for some variants of Azure SQL DB.
The bug was fixed in Microsoft ODBC Driver 17 Version number: 188.8.131.52. Updating your driver version to this will fix the issue.
