does not have the needed role he gets to see an error page for 401.2 not authorized. What I would like to accomplish now is to have a custom 401 page in my application and have it redirected there via settings in the web.config. I tried this: But this does not get caught. Do I have to override it in IIS instead? I hope not as web.config httperrors that would make getting things deployed harder. asp.net http-status-code-401 custom-errors share|improve this question asked Jan 13 '10 at 13:47 Nyla Pareska 70941732 add a comment| 4 Answers 4 active oldest votes up vote 7 down vote I ran into the same problem recently and it turns out that this is one of the quirks when using Windows Authentication. Joshua Flanagan created a nice HttpModule a while ago that will respect the customErrors section in your web.config and redirect to the 401 error page. The key to the solution is to intercept the EndRequest event of the page lifecycle, check for a 401 status code, and then execute your custom page. The portability of the HttpModule is nice because it makes the solution reusable, and keeps your Global.asax clean, but there's nothing stopping you from wiring up your EndRequest event in the Global.asax with his code if you really wanted to. If you're using ASP.NET MVC, the solution isn't quite as elegant. share|improve this answer answered Feb 6 '10 at 1:23 Ryan Rivest 947812 add a comment| up vote 3 down vote If you do not want to add an HttpModule in web.config in global.asax.cs protected void Application_EndRequest(object sender, EventArgs e) { HttpApplication application = (HttpApplication)sender; if (application.Response.StatusCode != 401 || !app

The site is secured by Windows authentication and that works fine: When users go to the site, they are asked for username/password and get http://serverfault.com/questions/458394/iis-7-5-how-to-configure-custom-authentication-error-page-with-windows-authenti through if authenticated. If users click Cancel or mistype password 3 times, they are shown 401 error page: Now I would like to show custom page explaining how to log-in. So I go to Error pages, select status code 401.2 and point it to the page I would like to display: Then make sure the custom errors are turned on for everybody. And kaa-boom! Authentication does not work any more, users are not presented with the password prompt. As documentation says, Windows Authentication works by sending 401 reply first, then browser asks user to provider credentials and then they work out what to do next. What happens here: on first request for the page IIS tries to send 401-header, but notices that web.config says "on 401 redirect to this page". And instead of authentication, it just gives the redirect page. I've tried replacing 401, 401.1, 401.2 - made no difference. What am I doing wrong and how to give custom page on user authentication error? p.s. Here is the web.config: http://blog.flimflan.com/HttpModuleToAllowACustomErrorPageFor4012AccessDeniedInASPNET.html different pages to display depending on the HTTP status code.I like to http://forums.codeguru.com/showthread.php?275304-Handle-401-2-Custom-Error-in-IIS take advantage of ASP.NET's declarative security model by defining the users and roles that are authorized to execute different parts of my website. For example, I can limit access to a page named Protected.aspx by declaring that all users must be a meber of the VerySpecialUsers group. This can custom error be accomplished by adding the following section to my web.config: I like this model as it allows me to easily modify the access restrictions for a page, and since it 401.2 custom error uses ASP.NET's Role Provider framework, it is not tied to any implementation about how role membership is determined. By default in a Windows Authentication/NTLM scenario, the roles map to the group memberships of your Windows login account (Administrators, Power Users, Users, etc). But you can very easily create your own Role Provider that retrieves group membership information from your own data store.When a user does not meet the authorization requirements to visit a certain page, ASP.NET will return a 401.2 Access Denied error. The page looks like the standard yellow screen of death (YSOD) that ASP.NET returns for all errors.The customErrors section of web.config is supposed to let you provide a friendlier response to your users so they never have to see the YSOD. You would think that all you need to do is define a page for the 401 status code in customErrors and all would be good. You would be wrong. You can even try changing the custom error page defined in your IIS settings, and it still won't work.The newsgroups have countless unanswered posts about this issue. Fortuna

If an unauthenticated user tries to access the web site, We get 401.2 error. I want to handle this error and redirect them to the Custom error page. For this I tried to use 1. Custom errors option in IIS. This works for 404 but not 401 2. element in web.config. (This works fine for other errors such as 404, 403 but not 401) 3. I even tried to give full access to the custom page with elements in web.config. Even that didnt work. Do you have any soultion for this?
