Windows Authentication not working in ASP.NET MVC 5 web app

Question

I have an ASP.NET MVC 5 app and am trying to enable Windows Authentication. The development machine is Windows Server 2008 R2, IIS Express 8.0, Visual Studio 2013 & .NET Fra

Answer 1

The ConfigureAuth method in Startup.Auth.cs contained the following code which needed to be removed for Windows Authentication.

The code is used for Forms Authentication with OWIN.

        // Enable the application to use a cookie to store information for the signed in user
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            LoginPath = new PathString("/Account/Login")
        });
        // Use a cookie to temporarily store information about a user logging in with a third party login provider
        app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

Answer 2

Just a heads up. You don't HAVE to remove cookie authentication entirely, although i did remove the externalsignincookie. Take a look at my project at https://github.com/vishnu4/AspNetMVC5WinAuth where I'm using OWIN and MVC5 to use windows authentication. Hopefully this helps anyone else trying to get it to work.
