I had the same problem and this worked for me. Thanks nbj
Hi,
I had the same problem
See if you have this error in /var/log/squid/cache.log:
"Login for user [domain]\[user]@[CC] failed due to [winbind client not authorized to use winbindd_pam_auth_crap. Ensure permissions on /var/cache/samba/winbindd_privileged are set correctly.]"
If so do:
chown -R root:squid /var/cache/samba/winbindd_privileged
/etc/init.d/winbind restart
It worked for me.
Regards
