title: HttpContext.Request.LogonUserIdentity.Groups Result
body: <p>I have configured my web application to run under windows authentication mode, I also used HttpContext.Request.LogonUserIdentity.Groups to retrieve a list of groups the logon user belongs to.</p>
  
  <p>When I compare my result with another tool from <a href="http://userviewer.sourceforge.net/" rel="nofollow">http://userviewer.sourceforge.net/</a> I actually see some differences (though most of them match).</p>
  
  <p>This leads me to think that are there any diferent type of AD groups in the directory that .Net API will pick on?</p>
  
  <p>The major difference I noticed is that HttpContext.Request.LogonUserIdentity.Groups does not return Distribution Group in general, but in some rare cases I also saw one distribution group returned.</p>
  
  <p>Thanks</p>
