Testing squid-2.6.STABLE20 on CentOS 5 with WinXP clients that are part of and AD domain. I have been testing the Kerberos authentication and have noticed that after a few days I can no longer use the proxy. My Kerberos tickets are valid on the proxy and on the client and I can access windows network resources normally. If I login to different machine I can use the proxy so all seems well with the proxy configuration. If I logout of the affected machine and then login again proxy access is restored. I have tested this with a few other users who have been logged in for over a week with the same results. All were denied access until logging out and in again. Time is correct on all machines. Any ideas for the best way to debug the Kerberos handshake. Thanks in advance. Dean.
