Using customuserservice sample of Identity Server V3 in MVC not able to redirect to login page

Question

I am using CustomUserService sample of Identity server v3. I added home controller as below - `public class HomeController : Controller { // // GET: /Home/ public ActionResult Index() { return View(); }

    [Authorize]
    public ActionResult About()
    {
        //ViewBag.Message = "Your application description page.";

        //return View();
        return View((User as ClaimsPrincipal).Claims);

    }`

And added 2 views About.cshtml and Index.cshtml. As you see About action has Authorize attribute. So when I navigate to About, I should get redirected to login page of Identity Server V3 however it is not happening so. My complete startup.cs is as follows -

public void Configuration(IAppBuilder app)
    {
        LogProvider.SetCurrentLogProvider(new DiagnosticsTraceLogProvider());

        app.Map("/core", coreApp =>
        {
            var factory = InMemoryFactory.Create(
                clients: Clients.Get(),
                scopes: Scopes.Get());

            // different examples of custom user services
            var userService = new RegisterFirstExternalRegistrationUserService();
            //var userService = new ExternalRegistrationUserService();
            //var userService = new EulaAtLoginUserService();
            //var userService = new LocalRegistrationUserService();

            factory.UserService = new Registration<IUserService>(resolver => userService);

            var options = new IdentityServerOptions
            {
                //IssuerUri = "https://idsrv3.com",
                IssuerUri = "https://localhost:44333/",
                SiteName = "Thinktecture IdentityServer3 - CustomUserService",
                //SigningCertificate = LoadCertificate(),
                SigningCertificate = Certificate.Get(),
                Factory = factory,
                CorsPolicy = CorsPolicy.AllowAll,

                AuthenticationOptions = new Thinktecture.IdentityServer.Core.Configuration.AuthenticationOptions
                {
                    IdentityProviders = ConfigureAdditionalIdentityProviders,
                    LoginPageLinks = new LoginPageLink[] { 
                        new LoginPageLink{
                            Text = "Register",
                            //Href = "~/localregistration"
                            Href = "localregistration"
                        }
                    }
                },

                EventsOptions = new EventsOptions
                {
                    RaiseSuccessEvents = true,
                    RaiseErrorEvents = true,
                    RaiseFailureEvents = true,
                    RaiseInformationEvents = true
                }
            };

            coreApp.UseIdentityServer(options);
        });

I am using CustomerUserService sample because, I want to use WSfederation. So ADFS wil provide claims to identity server and in turn Identity server should return those claims to About view. Can anyone help me here.

I ran into a similar situation, when there were errors during Identity Server initialization. I turned on logging in Web.config:

http://identityserver.github.io/Documentation/docs/configuration/logging.html

    <system.diagnostics>
      <trace autoflush="true" indentsize="4">
       <listeners>
        <add name="myListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="d:\logs\STS.log" />
        <remove name="Default" />
       </listeners>
      </trace>
     </system.diagnostics> 

Logs showed me that my certificate's key length was less than 2048 bits. You might have run into a different error which is logged as well.
