Error: 18456, Severity: 14, State: 5.
Reason: Could not find a login matching the name provided.
The AD group has rights to the default database the user is trying to log into, but no matter what I do, i have to register the user outside of the group for SQL to log in.
I also tried making the new AD group a local admin on the box hosting the sql instance, but I can't get this login to work as a member of the group on the box.
Scratching head... login is valid not locked out or anything.
