title: Can't login given Windows authentication and an AD group authorization
body: <p>I've read up on Authentication and Authorization for a web application, but I can't figure out what's going on with this. In the application's web.config file it shows Windows authentication, and the authorization allows the role "DL_RPM_Commissions_Partners". We have users who are in that role, however, who cannot get in to the application. The system keeps prompting them for their credentials, not accepting the correct ones.</p>
  
  <p>I realize this isn't a lot of detail for you, but I don't know what else to tell you up front. Please feel free to ask me questions that are pertinent to the problem, and I'll do my best to answer them. I need to get this resolved as soon as possible since legitimate users are being locked out of an essential application.</p>
  
  <p>Thanks!</p>
