Joost Thanks for pointing that out. Nearly killed my self reading it. HOWEVER the error is in the config I posted not my config, I just copied it off the squid website and edited it for my email and forgot to edit out the local part of the path. The actual lines in the config file are : auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic I also checked this path to make sure that was actually where the file was and it is correct. As a note it was one of the directories I gave the proxy group full privileges on.

Is this the exact message? Because there's a path mismatch between your config and the actual message. Are you sure you're editing the correct squid.conf file? Joost
