Windows Authentication - Get Current Username

Question

In my MVC application, I want to display the table in the cshtml file if the current user in the log is x people. I use Windows authentication and I made the following changes to the web.config file.

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

And in my controller, when I try to access the current username, I don't get any username. I am trying to do the following:

 ViewBag.LogInUserName = Request.RequestContext.HttpContext.User.Identity.Name; 

This line above worked. But I do not know what happened now. I have also posted my application on IIS now.

Answer 1

You need to put the [Authorize] attribute on your controller.

You can use User.Identity.Name in your controllers.

 [Authorize] public class YourController : Controller { public ActionResult SomeAction() { var userName = User.Identity.Name; } } 

Answer 2

Take a look at the properties of a web project, in particular:

• Anonymous Authentication - Set to Disabled
• Windows Authentication - Set to Enabled

By default, they are set opposite to what you are probably looking for.

Answer 3

A little late, but it may happen to others in the future.

I had the same problem after deploying my site on a new IIS server and anonymous authentication was enabled, so make sure that anonymous authentication is disabled and it should work.
