This sounds like a misconfiguration somewhere. A user may choose to logon
using SAM or UPN as the logon mechanisms will recognize both. Make sure the
user selects the correct domain name from the login dialog and SAM login
should work. If it doesn't there may be some security related issues
somewhere. Have you modified the security on the OU or the domain nodes in
Active Directory? Or any changes to the Builtin container?

I've seen occasions with the opposite problem where UPN logon may prevent a
user from changing his or her password if security is too strict.
