Token-based server access validation failed with an infrastructure error

Question

I would appreciate help with the following issue:

I have created a local group in our SQL 2008 server and added two Windows user accounts "DOMAIN\UserName" I then added the local group to the database and granted read only access.

The users are trying to link tables using MS Access using and ODBC connection and getting the following error. Users are not system administrators.

Answer 1

This sounds like an issue with Kerberos/windows authentication with your AD server(s). I would check with your AD admin to see if they can help you troubleshoot this one.

Answer 2

Thank you for your response.

I fount the cause of the problem. I just whished the MS error message in the logs could be more clear. The remote user with logging access problems was also part of a group that was denied access to our database. I completely overlooked this configuration. I then created a different group and granted access to the user. I also granted access explicitly and in both instances the users was denied access. Once I remove the group that denied access it all worked fine.
