title: Read Windows Logged in User to understand role
body: <p>I want to know the best way to implement it. I have a asp.net web app which does not have any login page/options. But I need to populate different options in the web page based on User roles (admin, Member etc..).
  How can I know what is the role of current user logged in on the windows machine. 
  Can I do this in my Java script page? or is there a way to retrieve it from IIS?</p>
