User.Identity.Name is empty when using Window authentication

Question

I have a website in MVC 4 with .net 4.5 running on IIS7 for example: www.mysite.com and a folder www.mysite.com/admin

the www.mysite.com is using form authentication and allow anonymous for certain pages, I would like to have www.mysite.com/admin using window authentication.

I have the setting in IIS security for that folder to use Window Authentication ( it is not an application in IIS )

In my admin Controller I need to capture the username from the domain and it is always empty the code is as followed:

   WindowsIdentity winId = WindowsIdentity.GetCurrent();         
  if (winId != null)
  {
   string name = winId.Name;        
  }

the User.Identity.Name is also empty Please let me know what am I missing.

I am sure that this is something pretty common and could not figure out why it does not work with MVC, i have the old site using web form and have the same setting and it is working.

Thanks In advance

If you are using windows authentication for the page try the following and see if it has any data. It sounds like you may have tried this but I didn't see the Page object included.

Make sure your web.config has windows auth enabled.

<authentication mode="Windows">
     </authentication>

string user = Page.User.Identity.Name;

Hope this helps I would probably look into the built in roles and membership features I'm not familiar with the route you are taking my apologies.
