Why this error?
We are encountering this error because the user has not been set as an Azure Active Directory admin yet, with whom we are trying to connect to the Azure SQL database.
Solution
You can use the steps below to set the user as an Active Directory admin, which will quickly resolve this error.
- Navigate to the SQL server and click on the Azure Active Directory link from the left navigation. You can see that the “No active Directory admin” option is enabled.

- To set the admin, click on the Set Admin button.

2. Select the AAD DC Administrators option and click the Select button.

3. Then, click the Save button to save the changes.

Now, you have successfully set up the Azure Active Directory admin. Then, try signing in again from the Power BI Desktop application to connect to the Azure SQL database; this time, you won’t encounter the above error.

This is the way you can fix the error “Requested tenant identifier ‘00000000-0000-0000-0000-000000000000’ is not valid. Tenant identifiers may not be an empty GUID” using the above instructions. Thanks for reading this article !!!
