LDAP身份验证和匿名用户使用相同的asp.net mvc页面

Question

I have some intranet asp.net mvc3 app ,which is available for both LDAP authenticated and anonymous users.All of them are using IE. One of the views should be available for both of them, depending on status some columns should be hidden,etc.
I don't want anonymous users to receive popup authentication dialog,but can't see no way of solving problem.If I add Authorize() attribute ,it forces anonymous user to input user/password, if I remove this attribute everyone is treated as anonymous.
How can be this obstacle solved?

Answer 1

In your controller check to see if the user is authenticated and perform actions based off that conclusion.

if (User.Identity.IsAuthenticated){
//Handle Case

}
