rack-cas-client

This middleware will redirect all unauthenticated requests to the specified cas server. After a successful authentication the cas server will redirect the user back to your application with a service ticket. This ticket is used to check the validity of the user's session on subsequent calls.

By default the user's login username is store in the session (session['cas']['user']). If your cas server is configured to send extra attributes (http://code.google.com/p/rubycas-server/wiki/HowToSendExtraUserAttributes), then they are accessible at (session['cas']['user_extra']).

To log user out, send a DELETE to /logout and the middleware will delete the user's session.

This middleware was inspired by the 'rubycas-client-rails' gem

  run lambda {|env|
    request = Rack::Request.new(env)
    [200, {'Content-Type' => 'text/html'}, ['<p>You are in '+"#{request.session['cas']['user']}"+' </p><p>Extra '+ "#{request.session['cas']['user_extra'].inspect}" +'</p><form action="/logout" method="post"><input type="hidden" name="_method" value="delete" /><input type="submit" value="out"/></form> ']]

Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
