Apache2 module to authenticate trough a CAS server

 Apache2::AuthCASSimple is an authentication module for Apache2/mod_perl2.
 .
 It allows you to authenticate users through a Yale CAS server. It means you
 don't need to give login/password if you've already authenticated with the
 CAS server: only tickets are exchanged between Web client, Apache2 server and
 CAS server. If you are not authenticated yet, you will be redirected to the
 CAS server login form.
