how to remove logout and loggedout paged from asp.net identityserver3 - asp.net

Question

I just want a simple single sign-on for my application and identityserver3 seen to be a good solution. three things i didn't like about it though the consent page, the logout and logged out pages. i manage to disable the consent page by setting these lines to the Clients.cs file
RequireConsent = false,
AllowRememberConsent = false,
i also added custom view following the docs on Custom View Service.
so now How do I disable the logout and loggedout pages so that it automatically send the user to the home page when they clicks the sign out button?

Answer 1

The documentation here will help you. You are interested in specifying a custom set of AuthenticationOptions. Within that, there are three properties of interest:
EnableSignOutPrompt
Indicates whether IdentityServer will show a confirmation page for sign-out. When a client initiates a sign-out, by default IdentityServer will ask the user for confirmation. This is a mitigation technique against “logout spam”. Defaults to true.
EnablePostSignOutAutoRedirect
Gets or sets a value indicating whether IdentityServer automatically redirects back to a validated post_logout_redirect_uri passed to the signout endpoint. Defaults to false.
PostSignOutAutoRedirectDelay
Gets or sets the delay (in seconds) before redirecting to a post_logout_redirect_uri. Defaults to 0.
Using these three settings you should be able to tweak IdentityServer3 to your liking.
For example, your Startup.cs may look like this:
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.Map("/identity", idsrvApp =>
{
idsrvApp.UseIdentityServer(new IdentityServerOptions
{
AuthenticationOptions = new AuthenticationOptions()
{
EnableSignOutPrompt = false,
EnablePostSignOutAutoRedirect = true,
PostSignOutAutoRedirectDelay = 0
},
EnableWelcomePage = false,
Factory = Factory.Get(),
SigningCertificate = Certificate.Get(),
SiteName = "Identity Server Example"
});
});
}
}
