How to use Samba ntlm_auth is the same since Squid-2.5/Samba-3.0 days.. 1. Install Samba and join the domain. 2. Set up a suitable system group for winbind authentication, and chgrp the Samba privileged_pipe directory to this, with at least x permission for the group. 3. Make your cache_effective_user member of the above group. 4. Configure squid.conf as you have done. Regards Henrik
