Les, Nils, Thank you for the response. I did look at mod_auth_kerb, but unfortunately it is dependent on browser type/version and assumes that your clients are all inside the firewall and can reach the Kerberos servers. For now, I need to authenticate through PAM to internal authentication servers (I could use MySQL or RADIUS, too). The client has to have a valid username and password before accessing the page. So, I'm looking for feedback on any other Apache modules that allow PAM authentication. These are the only three that I have found: mod_auth_pamacea mod_auth_pamport mod_auth_pam If mod_auth_pam is the most stable of the three and nobody has had any bad experiences with it, I am willing to use it in a production environment.
