title: Is it possible to access claims from the client?
body: <p>Say I have a vanilla ASP.NET MVC web app using claims-based authentication. The server has access to claims easily enough from the controller's <code>User</code> property. But say I wanted to access the claims in the frontend, is that possible? Or do I need to expose a route on my controller which I would invoke with ajax from the frontend to retrieve the claims?</p>
  
  <p>Then let's ratchet it up a notch: instead of a vanilla app, I'm using Thinktecture's IdentityServer as the identity provider and WS-Federation to authenticate from my app (on a different domain). Is it possible then?</p>
