To secure a symfony application:

  * Enable the cas module in your `settings.yml`

        all:
          .settings:
            enabled_modules:      [ ... , cas]

    Do not secure `cas` module, it is the module that allows the user to log in and out.

  * Change the default login and secure modules in `settings.yml`

        .actions:
          login_module:           cas
          login_action:           login
        
  * Change the user class in `factories.yml`

        all:
          user:
            class: sfCASUser
        test:
          user:
            class: sfCASTestUser

  * You're done. Now, if you try to access a secure page, you will be redirected to the CAS server login page.
