title: How can you use Active Federation to authenticate with an ASP.NET MVC application?
body: <p>I have a WPF application that is using WS-Trust Active Federation over WCF.  When the user logs in, the application requests a token from the STS, caches it, and then provides that token to all WCF service calls which require authentication.  This application also has a Web Browser View that points to an MVC application that provides additional functionality.  I would like to be able to authenticate with the MVC app the same way I do with my WCF services, and provide the app with the same cached token I am using for all my other service calls.</p>
  
  <p>I know how to set up Passive Federation with an MVC app, but is it possible to perform Active Federation for an MVC app using Windows Identity Foundation?  </p>
