title: IsAuthenticated is true but HttpContext.Current.User.Identity.IsAuthenticated is False
body: <p>We are trying to implement Single sign on (sso) using SAML 2.0 using ADFS with our customer site.I have successfully set up ADFS and when i access ../adfs/ls/idpinitiatedsignon.aspx page it shows "Sign in to this site" radio button and it redirect to customer site and asks for Username and password and once entered customer's site user name and password then it brings back to idpinitiatedsignon.aspx and says "You are signed in" and shows sign out button.But i'm unable to get the logged in user's details from <code>HttpContext.Current.User</code> in idpinitiatedsignon.aspx because <code>HttpContext.Current.User.Identity.IsAuthenticated</code> is false but <code>IsAuthenticated</code>is true. So how can i get the logged in user information ?</p>
