Hello to everybody
I have an Episerver Version=7.5.394.2 running on a Windows Server 2008 R2 OS. A few days ago, I did a restore of the site and I need to configure Windows authentication mode but It is not working. When I log in to my site using Windows authentication or Sql server authentication I can access but It is not giving the User session data. If I go to My User Settings It doesn't show My user name or my Email. When I'm in the Login page if I introduce an incorrect password  It throws an authentication error which says "Login Failed" indicating that It is validating my credentials. I'm just no sure why It doesn't show the current user data in session.

If somebody have gone through similar situation and can help me with this, please let me know it, I will be very thankfull.
