title: Displaying the current authenticated Sharepoint user from an asp.net Page Viewer Web Part
body: <p>I am creating a standalone asp.net page that needs to be embedded into a sharepoint site using the Page Viewer Web Part.  The asp.net page is published to the same server on a different port, giving me the URL to embed.</p>
  
  <p>The requirement is that after a user is authenticated using Sharepoint authentication, they navigate to a page containing the asp.net web part for more options.  </p>
  
  <p>What I need to do from this asp.net page is query Sharepoint for the currently authenticated username, then display this on the page from the asp.net code.  </p>
  
  <p>This all works fine when I debug the application from VS, but when published and displayed though Sharepoint, I always get NULL as the user.  </p>
  
  <p>Any suggestions on the best way to get this to work would be much appreciated.</p>
