Redirect to another page when user is not authorized in mvc3

I’ve read

How to easily redirect if not authenticated in MVC 3? and
Redirect to AccessDenied page when user is not authorized but the link from an answer (means doesn’t work.

I put

[Authorize(Users = "test")]
    public class RestrictedPageController: Controller

        public ActionResult Index()
           return View();


And in my web.config, I have already
 <authentication mode="Forms">
      <forms loginUrl="~/Account/LogOn" timeout="2880" />

accordingly with

But when I want to access /RestrictedPage/Index, it must redirect me to other page (from other controller). Instead of this, the error appears like:

Server Error in '/Project' Application.

The view 'LogOn' or its master was not found or no view engine supports the searched locations. The following locations were searched:

Before login, the Logon page form appears correctly but the above error appears when accessing /RestrictedPage/Index page. I can login with user different one authorized to access RestrictedPage page.

Where is my mistake and how setup redirection ?


Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.

Method 1

The default Authorize attribute behaves in such a way that when the user is not authenticated or authenticated but not authorized then it set the status code as 401 (UnAuthorized). When the filter sets the status code as 401 the ASP.NET framework checks if the website has forms authentication enabled and if it is then redirects to loginUrl parameter set up there.

If you want to change that behavior say you want to redirect the user to an AccessDenied controller if the user is authenticated but not authorized then you have to extend the Authorize attribute and override the HandleUnauthorizedRequest method.

For ex.

public class CustomAuthorize: AuthorizeAttribute
    protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
        if (!filterContext.HttpContext.User.Identity.IsAuthenticated)
            filterContext.Result = new HttpUnauthorizedResult();
           filterContext.Result = new RedirectToRouteResult(new 
               RouteValueDictionary(new { controller = "AccessDenied" }));

You can override the HandleUnauthorizedRequest as per your need and then you have to mark the controller actions to use the CustomAuthorize attribute instead of the built-in one.

Method 2

I like Mark’s Answer,
but I don’t want to change all of my action attributes
from [Authorize] to [CustomAuthorize]

I edit Login() action on AccountController
and check Request.IsAuthenticated before show view
I think, if the authenticated user go to /Account/Logon,
I will redirect to /Error/AccessDenied.

    public ActionResult Login(string returnUrl)
        if (Request.IsAuthenticated)
            return RedirectToAction("AccessDenied", "Error");

        ViewBag.ReturnUrl = returnUrl;

        return View();

Method 3

Place “/Account/LogOn” Instead of “~/Account/LogOn”

Method 4

Since I did not want to override AuthorizeAttribute I used filter

public class RedirectFilter : ActionFilterAttribute
   public override void OnActionExecuting(ActionExecutingContext filterContext)

        if (!IsAuthorized(filterContext))
            filterContext.Result =
                new RedirectToRouteResult(new RouteValueDictionary(new {controller = "AccessDenied"}));

    private bool IsAuthorized(ActionExecutingContext filterContext)
        var descriptor = filterContext.ActionDescriptor;
        var authorizeAttr = descriptor.GetCustomAttributes(typeof(AuthorizeAttribute), false).FirstOrDefault() as AuthorizeAttribute;

        if (authorizeAttr != null)
            return false;
        return true;


Method 5

Yes, it is correct as you mentioned in web.config

<forms loginUrl="~/Account/LogOn" timeout="2880" />

redirection is looking for Account controller and LogOn actionresult. If you want to redirect your page, change there instead of account and logon
