Asp Net Mvc 5 Custom Identity
error handling for 404, 401 and other exceptions up vote 3 down vote favorite I'm struggling to understand how to correctly handle errors in ASP.NET MVC4. As an example, I've created a new MVC4 project using the "Internet Application" template and updated my home controller to test out some error cases: public class HomeController : Controller { public ActionResult Index() { ViewBag.Message = "Hello"; asp net mvc 5 custom usermanager return View(); } public ActionResult About() { throw new HttpException(401, "Not Authorized"); } public ActionResult Contact() { throw new Exception("Oh no, some error occurred..."); } } I have enabled customErrors in my web.config file:

Now, when an authenticated user opens a page - he is automatically authenticated. I have faced a problem - when a non-authenticated user (for example, a Mozilla Firefox user with not defined network.automatic-ntlm-auth.trusted-uris property) opens a page, IIS sends 401 response and prompts http://stackoverflow.com/questions/32139662/asp-net-windowsauthentication-custom-401-unauthorized-error-page for a login \ password. What I want is not to prompt him for a login \ password - just show a custom error page. It sounds pretty simple - authenticated users get the requested page, non-authenticated are redirected to a custom error page. It would work fine for FormsAuthentication. However, I have tried so many ways by now. Any Web.config redirects are not working. Even if I clear a Response and put there a redirect - I will get a loop because this custom page (*e.g., /Error/AccessDenied) also requires authentication. Marking a controller as AllowAnonymous does nothing. However, if I enable Anonymous authentication in IIS Manager, real authenticated domain users are not being authorized when they open a web-site. How can I solve this problem? c# asp.net asp.net-mvc authentication windows-authentication share|improve this question edited Aug 24 '15 at 9:55 asked Aug 21 '15 at 11:53 Yeldar Kurmangaliyev 16.3k72149 You want non-IE users to be redirect to another page?

This article answers a simple question: What to do when custom error page for error 401 in web.config is not working? How to replace the default ASP.NET "Access denied" page? Download source files - 13.5 Kb Introduction If you have an ASP.NET application with authentication mode set to Windows:
Page 401 Access Denied when Using Windows Authentication ASP.NET provides us with the ability to add custom pages for HTTP errors via Web.config CustomErrors tag. This however does not work when we try to handle the 401 error under Windows authentication. The reason for this is that this error (401) is raised during the Authorization request event on the HttpApplication process pipeline (see below), and Custom error settings are processed during the Action Method invocation (ASP.NET Handler.ProcessRequest event). HTTP Process Pipeline HTTP 401 Error browser Interaction The common interaction between the browser and the server is as follows: The browser sends request with no authentication tokens. The server responds with a 401.2 HTTP error. The browser send authentication tokens if the user is already logged. If the user is not, the browser shows a login dialog. Even if the user is logged on, but he does not have the required role for this access, the server returns a 401.2 error and displays the Access Denied Page. To provide a custom page for the Access Denied error, we should implement the following:Use httpErrors Configuration settings Allow Anonymous Access to content Allow Anonymous Access to controller actions Use httpErrors Configuration settings
