Answer 1

In one of my project, I use the code from uvita.

I have ASP.NET MVC2 and I use Active Directory authentication without login page. I have a NoAuth.aspx page that use site master page, integrate the web application layout.

This is the web.config.

The new class CustomAutorizeAttribute

using System.Web.Mvc;
public class CustomAuthorizeAttribute : AuthorizeAttribute
{
    protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
    {
        if (!filterContext.HttpContext.User.Identity.IsAuthenticated)
        {
            base.HandleUnauthorizedRequest(filterContext);
        }
        else
        {
           filterContext.Result = new ViewResult { ViewName = "NoAuth"};
        }
    }
}

and the controller

[CustomAuthorize(Roles = "ADRole")]
public class HomeController : Controller
{
    public HomeController()
    {
    }
}
