I suggest also using a current Firefox release. I am finding the 4x's
series work a lot better than the earlier 3x's did on Windows 7.
Kerberos also uses the USER at DOMAIN format for user labeling. Sending it
Basic USERID) or NTLM (DOMAIN/USERID) formatted labels may be the problem.
Kerberos and NTLM are both PITA protocols. But NTLM makes everything
worse. If you are able to avoid using it at all and to actively turn
NTLM off around your network the Kerberos side of things will work better.
