title: Using the Authorize attribute with Azure Active Directory
body: <p>I'm trying to use [Authorize(Roles="test")] and/or call User.IsInRole("test") on a testing app and it's not working for me.  In the app configuration in the Azure Management Portal I've enabled the SecurityGroup claim in the app manifest and also set the delegated permissions to allow for "Read all groups" and "Read directory data".  After doing this I'm able to see the SID for the test group in (ClaimsPrincipal.Current.Identity as ClaimsIdentity).FindAll("groups"), but the Authorize attribute and call to IsInRole are not working.  Is anything else necessary to allow this to work?</p>
