DotNetOpenAuth Failing to work on Live Server

问题

I worked on a sample application integrating OpenID into ASP.NET Web Forms. It works fine when hosted locally on my machine. However, when I uploaded the application to a live server, it started giving "Login Failed".

You can try a sample here: http://samples.bhaidar.net/openidsso

Any ideas?

Here is the source code that fails to process the OpenID response:

   private void HandleOpenIdProviderResponse()
    {
        // Define a new instance of OpenIdRelyingParty class
        using (var openid = new OpenIdRelyingParty())
        {
            // Get authentication response from OpenId Provider Create IAuthenticationResponse instance to be used
            // to retreive the response from OP
            var response = openid.GetResponse();

            // No authentication request was sent
            if (response == null) return;

            switch (response.Status)
            {
                // If user was authenticated
                case AuthenticationStatus.Authenticated:
                    // This is where you would look for any OpenID extension responses included
                    // in the authentication assertion.
                    var fetchResponse = response.GetExtension<FetchResponse>();

                    // Store the "Queried Fields"
                    Session["FetchResponse"] = fetchResponse;

                    // Use FormsAuthentication to tell ASP.NET that the user is now logged in,
                    // with the OpenID Claimed Identifier as their username.
                    FormsAuthentication.RedirectFromLoginPage(response.ClaimedIdentifier, false);
                    break;
                // User has cancelled the OpenID Dance
                case AuthenticationStatus.Canceled:
                    this.loginCanceledLabel.Visible = true;
                    break;
                // Authentication failed
                case AuthenticationStatus.Failed:
                    this.loginFailedLabel.Visible = true;
                    break;
            }

        }

回答1:

Turn on logging on your live server and inspect them for additional diagnostics. It's most likely a firewall or permissions problem on your server that prevents outbound HTTP requests.

You may also find it useful to look at the IAuthenticationResponse.Exception property when an authentication fails for clues.

As Andrew suggested, check the exception. In my case, my production server's time & date were off and it wouldn't authenticate because the ticket expired.
