Description:
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.
