I realized from a previous question that I had been asking the wrong question...I would like to turn my application into a CAS server so that admins of the application may use this same authentication mechanism to log into other applications that we develop for the organization.
Have you done this before? Is there a plugin which adds the ability to Devise to be able to act as a CAS server? What do I need to change/add in order to turn the app into a CAS server?
