All solved! Seem that kerberos is ALWAYS not working only on a specific worstation. If i use kerberos from any other pc it works as excepted. What can cause the error on that specific workstation? I've reinstalled the os due to this problem, and it's still there (os preinstalled, so i've used the recovery procedure from hp, maybe the problem is in the recovery os image) -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Kerberos-auth-not-working-tp4667646p4667648.html Sent from the Squid - Users mailing list archive at Nabble.com. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
