Hello, I'm having some trouble setting up the latest version of SquidNT (2.6STABLE9) as a reverse proxy and have it passthrough Kerberos/NTLM to an IIS 6 web server that is serving pages with "Windows Integrated Authentication" enabled. I did find this thread on the mailing list, so I do know that this is possible with Squid 2.6: http://www.mail-archive.com/squid-users@xxxxxxxxxxxxxxx/msg41910.html Unfortunately, the thread didn't really detail what the final fix was. The important settings in my squid.conf are as follows: client and server persistent connections are enabled no-connection-auth is not set on http_port connection-auth is set to on on cache_peer login=PASS is set on cache_peer The reverse proxy does serve non-windows integrated authentication pages fine (anonymous pages), and it even served digest pages ok. But when I load a WIA page, I get prompted for a username and password. If I supply it with a username and password, it fails. Any help would be appreciated. Thanks, Caleb Anthony
