title: Given Access Token, how can I get domain / name of Windows Azure Active Directory
body: <p>I am using the Windows Azure Management Libraries and is getting a list of subscriptions and the WAAD tenant id (a guid) for each subscription. This means I just need to sign in to the WAAD to get permision to manage my subscriptions.</p>
  
  <p>I am developing an application and guids are not that pritty in the UI so I am looking for some C# code or just just the rest call I can query for the name.</p>
  
  <p>I have a access token from the AuthenticatinoContext of Microsoft.IdentityModel.Clients.ActiveDirectory</p>
