Hi, We're using Squid-2.5.STABLE14 and occasionally when we rotate logs (nightly event) something breaks in the squid->ntlm_auth->winbind chain such that users get prompted in their browsers to authenticate. In the cache log we see this error for each user: Login for user [domain]\[user]@[machine] failed due to [winbind client not authorized to use winbindd_pam_auth_crap. Ensure permissions on /appl/samba-3.2.10/var/locks/winbindd_privileged are set correctly.] The permissions are of course correct on the winbindd_privileged folder and the pipe (this works most of the time) drwxr-x--- 2 root squid 3 Dec 3 22:29 /appl/samba/var/locks/winbindd_privileged srwxrwxrwx 1 root root 0 Dec 3 22:29 pipe Squid runs as effective user 'operator' which is in the 'squid' group. When the problem happens I shutdown Squid and restart it and everything works once again. Thanks for looking. Rob
