Hi Squid Users. I've got a successful squid cache using 2.5-STABLE9 with NTLM auth and wbinfo_group.pl for NT group enumeration. The squid is connected to an upstream ISA cluster hosted by my district authority, with a username and password to access. I am currently filtering with ACLs to give varied levels of access for Students (trusted and un-trusted) and Staff, based on NT group membership. I now have an option to use a different user account for Staff on the upstream so they have less filtering on the ISA cluster (over and above local squid filtering). I'd basically like to evaluate if a user is in the "Staff" NT group and if so use a different username to the same upstream proxy. Is this possible? Reading the web, cache_peer_access may help, but I'm not sure if that would function for the same proxy address.
