I'm running Squid 3.0 Stable 21. I have two reverse proxy sites setup with LDAP authentication enabled. When I access either site, authentication works fine. My problem is when I'm authenticated to one site and access something on the other site, I get prompted to authenticate again. I can't figure out why. Any help is appreciated. Below is my squid.con settings. acl ldap-auth proxy_auth REQUIRED http_access allow ldap-auth http_port x.x.x.x:80 accel defaultsite=intranet.cadc.circdc.dcn cache_peer x.x.x.x parent 80 0 no-query originserver name=intranet1 round-robin cache_peer x.x.x.x parent 80 0 no-query originserver name=intranet2 round-robin acl sites_intranet dstdomain intranet.cadc.circdc.dcn http_access allow sites_intranet cache_peer_access intranet1 allow sites_intranet cache_peer_access intranet2 allow sites_intranet http_port x.x.x.x:80 accel defaultsite=www.cadc.circdc.dcn cache_peer x.x.x.x parent 80 0 no-query originserver name=iis acl sites_iis dstdomain www.cadc.circdc.dcn http_access allow sites_iis cache_peer_access iis allow sites_iis http_access deny all Mike Grasso Data Network Administrator DC Circuit Court of Appeals (202) 216-7443
