title: Is it possible to disable authorization on one action in an MVC controller?
body: <p>I have an authorization attribute on a controller, but I'd like to turn it off on one action.
  I created my own authorization filter and added "Anonymous" into the Roles list.  In my filter I then return true if Anonymous appears in the role list.</p>
  
  <p>However, it doesn't seem to get past the login page as if the controller authorization is pre-empting anything else.</p>
