Hi Pedro, Good to know you solved it. From your post it sounded like XP worked and Win 7 didn’t

Hi Markus, I initially had it configured as such and changed it to auth_param negotiate program /usr/lib/squid3/negotiate_kerberos_auth -d -r -s HTTP/proxy01tst.fake.net as a troubleshooting step. I've since then changed it back. Dan pointed out earlier that it could be a permissions problem, and sure enough, permissions on /etc/squid3/PROXY.keytab were wrong (group had no read permissions). Fixing that seems to have sorted out the problem. I'll be doing more extensive testes on Monday when the test group start surfing the web. Thanks for all the help!

Can you try auth_param negotiate program /usr/lib/squid3/negotiate_kerberos_auth -d -r -s GSS_C_NO_NAME instead of auth_param negotiate program /usr/lib/squid3/negotiate_kerberos_auth -d -r -s HTTP/proxy01tst.fake.net Markus "Pedro Lobo" pal...@gmail.com wrote in message news:fd6832b9-3f1f-48c6-a76f-47a224f16...@gmail.com...

We've got a production environment with a couple of squid 2.7 servers using NTLM and basic authentication. Recently though, we decided to upgrade and I'm now setting up squid 3.3 with Kerberos and NTLM Fallback. I've followed just about every guide I could find and in my testing environment, things were working great. Now that I've hooked it up to the main domain, things are awry. If I use a machine that's not part of the domain, NTLM kicks in and I can surf the web fine. If I use a Windows XP or Windows Server 2003, kerberos works just fine, however, if I use a machine Windows 7, 8 or 2008 server, I keep getting a popup asking me to authenticate and even then, it's and endless loop until it fails. My cache.log is littered with: negotiate_kerberos_auth.cc(200): pid=1607 :2014/10/24 23:03:01| negotiate_kerberos_auth: ERROR: gss_accept_sec_context() failed: Unspecified GSS failure. Minor code may provide more information. 2014/10/24 23:03:01| ERROR: Negotiate Authentication validating user. Error returned 'BH gss_accept_sec_context() failed: Unspecified GSS failure. Minor code may provide more information. ' The odd thing, is that this has worked before. Help me Obi Wan... You're my only hope! :) Current Setup Squid 3.3 running on Ubuntu 14.04 server.
