title: ASP.NET Login Control with Active Directory Membership Provider
body: <p>I have setup a basic application which uses the ActiveDirectoryMembershipProvider to talk to our AD and authenticate users. It's a simple login page with the control which redirects me to a simple output of who is logged in and associated ticket information, this works great and when I test it on my development machine it just works.</p>
  
  <p>However if I deploy this to the webserver under a virtual directory, it simple refuses to direct or even acknowledge that there ticket is a valid ticket, it just refreshes back to the login page. If I type in rubbish credentials it actually recognises this and tells me there';s an error, but if I login successfully it just refreshes the page. When I manually go the information page it treats me as an unauthenticated user! </p>
  
  <p>This is most puzzling! Any help would be greatly appreciated!</p>
  
  <p>Thanks</p>
