[squid-users] Re: squid_kerb_auth: Unspecified GSS failure (W2K8)

Hi Mihail,

   What does a klist -ekt <keytab> show ? ( I assume you use MIT Kerberos
on the squid server)

   What do you see with wireshark in the authentication header send to squid
?

I don't know why access-time is not being updated, but strace has
shown that keytab is being read successfully by squid_kerb_auth
