This is pertaining to SDL Tridion 2013 SP1. We are not using LDAP, instead Active Directory.
The userids are appearing in the Trustees table as well as correct privileges in the TCM Admin as System Admin.
However we are still getting this error below:
401 - Unauthorized: Access is denied due to invalid credentials. You do not have permission to view this directory or page using the credentials that you supplied.
Any thoughts on why this error would be occurring?
We can also log into our sandbox with our AD credentials on a Windows 2008 vm, but we cannot login with our AD credentials on a Windows 2012 vm..
Here is a picture of the Tridion Logs:
