So I am helping with some work and we have built a few servers in Azure with their SQL server image. Everything seems healthy apart from when adding an AD group for the domain admins to access SQL i get the following error below. I can add the users in individually however thats not very practical.

AD group is Universal and a security group however i did also try creating a global group but that did not work either.

Server is configures with SQL and Windows Auth and SQL is 15.0.4188.2

===================================

Cannot connect to W-P-SQL-VM-04.

Login failed for user '****\RS_Admin'. (.Net SqlClient Data Provider)

    You'll want to look at the state from the SQL Errorlog and not this error. Most likely it's a permissions issue as group logins have permissions applied from all relevant groups. Dec 21, 2021 at 11:49

    Use the user also a member of a group with a deny permission? Dec 21, 2021 at 15:07

A very basic thing but when you say "AD", do you mean Azure AD (AAD) or on-prem AD? Azure SQL Database supports Azure AD, so if your group isn't available in AAD (e.g. it hasn't been synchronised from on-prem AD), that could be your problem.
