title: Authenticating directly to an Azure ACS identity provider
body: <p>I need my mobile application to allow authenticating either to 3rd party vendor (facebook, google, etc) or to my own WS-Federation identity provider (I'm using Thinktecture). Now, when logging in to my own WS-Fed idp I want to authenticate directly and pass the security token to Azure ACS (and not by using a dedicated login page). I need that because I don't want my users to authenticate using my provider by using a dedicated web page (and moving out of the context of the application).</p>
  
  <p>Your help will be appreciated.</p>
