title: User.IsInRole returning false
body: <p>My ASP.NET app is using windows authentication.  If I run the following code:</p>
  
  <pre><code>WindowsIdentity wi = (WindowsIdentity)User.Identity;
  
  foreach (IdentityReference r in wi.Groups)
  {
      ListBox1.Items.Add(r.Translate (typeof (NTAccount)).Value);
  }
  
  if (User.IsInRole ("Everyone"))
      Label1.Text = "Is in role";
  </code></pre>
  
  <p>The listbox will contain the name of every group the user belongs to.  If I then call <code>User.IsInRole</code>, and pass in the name of any of those groups, I always get a false.  </p>
  
  <p>Can anyone tell me what I am doing wrong?</p>
  
  <p>Thanks</p>
