If your CNTLM was running on the Squid machine and using the credentials for the service account you have setup Squid to use now - then the cache_peer login=NEGOTIATE should make Squid operate as equivalent to what CNTLM was doing. The config file would be useful for anyone who follows up (not just me, who will be out of time shortly for another few days). Also, if you can track what HTTP messages are happening and whether the Kerberos is working properly for the Squid->parent messages it would be useful. The current Squid can provide HTTP details in cache.log with "debug_options 11,2". I'm not sure how you would test the Kerberos on a Windows installation, but the Negotiate auth headers in those messages might give a few clues anyway.
