Asp.net MVC 5 redirect to Account/Login

Question

I'm learning ASP.NET MVC. I have MVC version 5.2.2.0

I attached Authorize attribute to an action method Index() in Employee controller.

In the Web.config file, I changed authentication tag data as follows:

<system.web>
    <authentication mode="Forms">
        <forms loginurl="~/Authentication/Login"></forms>
    </authentication>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />
</system.web>

What is expected is that when localhost:port/Employee/Index is accessed, the user should be redirected to localhost:port/Authentication/Login

But it is redirecting to localhost:port/Account/Login

By looking at other links, I tried the following things:

1.Added

<add key="autoFormsAuthentication" value="false" />
<add key="enableSimpleMembership" value="false"/>
<add key="loginUrl" value="~/Authentication/Login" />
<add key="PreserveLoginUrl" value="true" />

to appSettings section of Web.config

2.Changed IIS 8 Anonymous Authentication from Specific User to Application Pool Identity

3.When the above two didn't work, I changed authentication tag to

<authentication mode="Windows" />

But none worked.

EDIT Don't do the things 1, 2, 3 I mentioned above. Just do the changes mentioned in the answer

Answer 1

The problem is that you will have the OWIN middleware configured by default to redirect to "/Account/Login" for cookie authentication.

Open /AppStart/Startup.Auth.cs and edit the following block of code to target our own URL :-

app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/Account/Login"),
                Provider = new CookieAuthenticationProvider
                {
                    // Enables the application to validate the security stamp when the user logs in.
                    // This is a security feature which is used when you change a password or add an external login to your account.  
                    OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
                        validateInterval: TimeSpan.FromMinutes(30),
                        regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
                }
            });            
            app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
