How to get username input from Windows Authentication in IIS?

Question

In IIS I have the authentication set to Windows.

2 Questions:

1. Is there a way that I can grab the username that was entered by the user for that pop-up authentication window before it loads the page and

2. Is there a way I can make it so that the login is required every time they visit the page?

Thanks.

Answer 1

To answer your first question this is how you access the user from a windows authentication:

WindowsPrincipal winPrincipal = (WindowsPrincipal)HttpContext.Current.User;

There are other options like:

WindowsIdentity winId = WindowsIdentity.GetCurrent();
WindowsPrincipal winPrincipal = new WindowsPrincipal(winId);

Or

WindowsPrincipal winPrincipal = (WindowsPrincipal) Thread.CurrentPrincipal();
