I had squid running fine on FC4 using pam_auth. I upgraded the server to FC9 a few days ago and unfortunately I can not get it to work any more. FC9 has squid 3.0 STABLE2. The relevant portions of squid.conf are: auth_param basic program /usr/lib/squid/pam_auth auth_param basic children 5 auth_param basic realm aradhana auth_param basic credentialsttl 2 hour auth_param basic casesensitive off .... acl logueados proxy_auth REQUIRED ..... http_access allow logueados http_access allow localhost http_access deny all There is a squid file in /etc/pam.d with a line for account and a line for auth. I also tried this using ncsa_auth. The problem is that the browser does not ask for a login but goes directly to the 407 error page saying that access to the cache is denied. This happens with IE and Firefox. These same browsers were working a few days ago with the older version. I also tested pam_auth manually on the command line and it works. Any clues about what needs to be done in version3? Miguel
