Domain User Auth

  • I have a user, who is part of a group (that has access to SQL Server) cannot login to SQL Server. But when I add the user directly as a login in SQL Server, he can log right in.

    Any one see this before?

  • Yes I have on 2000 or 2005 (can't remember which one as it was a couple of years ago). The user ended up rebooting and then it worked. Not sure why it worked, but it did. Let us know if it works for you.

  • Could be because the user was added to the group a few minutes before. If your group membership changes after you log in, your token doesn't automatically update, and you have to log off/on to regenerate the token. And maybe that's what's happening here as well -- the described behavior would certainly happen here.

    Another flaky circumstance can happen if a user changes their password but doesn't log off/on again. I have seen that generate login failures but in that case it would fail for all attempts to log in including giving the user their own login.

  • Apparently, user has rebooted the machine already, and had not reset their password. The reboot should have updated the access token information as well.

    I will drop the group and re-add it to SQL Server and see if that helps.
