As of now AAD does not have a mechanism to login/authenticate SQL server using gMSA accounts. Is this planned in future?
Actually, you may want to check out this existing suggestion in the MIM category: https://feedback.azure.com/forums/169401/suggestions/18395203
Hi Sonali, I'd recommend opening this in the SQL Server forum here: https://feedback.azure.com/forums/908035-sql-server. You're likely to get much more support from the community there, and they can route requests our way.
