SQL 2012 server login using windows authentication

Posted on 2014-03-27
Last Modified: 2015-09-15
I’ve added some active directory groups to security\logins in management studio. The groups have public and sysadmin roles enabled. Despite this, when I log into the windows server using one of the members of these groups I am unable to login to SQL.

Any suggestions?

Are the groups you've added to SQL Server actually security groups, or are they "Distribution Groups" in Active Directory? SSMS will let you assign rights to either, but distribution groups can't be evaluated for security membership and the user won't appear to have any of the rights you'd expect. You need to ensure you're using a security group to assign your rights.

Assigning rights directly to a user in SQL Server should always work as expected - I don't believe there are any exceptions there.

I will defer to Ryan, but he made some valid points that I think should be kept in the knowledge base.  So I would suggest Accept http:#a40047369

I come across this issue commonly, so I think it would make sense to come up as a search result. It seems to trip people up (myself included, before I figured it out) pretty frequently.

That said, I'm also fine if the question is considered unresolved and deleted - so I'll defer back :)
