repoze.who.cas is a repoze.who plugin that allows the use of a CAS < server as an authentication provider. It allows you to specify a CAS server against which your users can authenticate. Once they authenticate against the CAS server, they'll be redirected to your application in such a way that their identity will be injected into the WSGI environment with a key that you can specify.

Example who.ini

[plugin:cas] use = repoze.who.plugins.cas:make_plugin cookie_name = someapp-cas secret = ahardtoguessthing cas_login_url = cas_validate_url =

[general] request_classifier = repoze.who.classifiers:default_request_classifier challenge_decider = repoze.who.classifiers:default_challenge_decider remote_user_key = REMOTE_USER

[identifiers] plugins = cas

[authenticators] plugins = cas
