title: DNN and windows authentication
body: <p>I'm trying to achieve the simplest functionality related to windows authentication in DotNetNuke. What I need is just the user to be authenticated using windows authentication when accessing DNN site (no need for user to be logged in within DNN) and read his username (HttpContext.User.Identity.Name). </p>
  
  <p>How can I achieve this as simple as possible?</p>
  
  <p>Is it possible without using any 3rd party authentication providers e.g. <a href="http://dnnauthad.codeplex.com/" rel="nofollow">DNN Auth: Active Directory</a>?</p>
