Aloha, I recently downloaded Squid 3 stable 10 and installed it to my CentOS 5.2 VM. It's running great already, so now I'm looking to auth users either directly via A.D. or via RADIUS. My google-fu turns up a ton of examples for Squid 2.6, which don't seem to work for Squid 3. Does anyone have experience using Squid 3 to auth clients against AD either via the ntlm_auth (which when I enable, instantly crashes squid) or via squid_radius_auth ? Thanks! Rick Payton, I.T.
