authentication

I'm following This tutorial to implement my own ASP.NET authentication. At first I want to make this code able to run, then Debug to see how the flow is going, but I'm being stuck at the beginning, the principalService and context is always is null event I have regiser in Unityconfig.cs.

Global.asax

public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
        }
        protected void Application_AuthenticateRequest(object sender, EventArgs e)
        {
            var principalService = DependencyResolver.Current.GetService<IPrincipalService>(); // always null
            var context = DependencyResolver.Current.GetService<HttpContextBase>(); // always null
            // Set the HttpContext's User to our IPrincipal
            context.User = principalService.GetCurrent();
        }
    }

UnityConfig.cs

public static void RegisterTypes(IUnityContainer container)
        {
            container
               .RegisterType<IPrincipalService, MuchoSupportPrincipalService>();
        }
