For an application, I need to have a SSL certificate for a WCF service,
So we installed it. If I go with an internet browser with a web browser trough https, I've got no problem, no warning, nothing, so I suppose that this certificate is considered as valid for windows.
The problem is that when I'm trying to connect to my WCF server, I got this error:
The X.509 certificate CN=myHostName, OU=tom, O=myDomainName,L=MyLocation, S=SO, C=CH chain building failed. The certificate that was used has a trust chain that cannot be verified. Replace the certificate or change the certificateValidationMode. The revocation function was unable to check revocation because the revocation server was offline.
What can be wrong? How can I know which part of the chain is unvalid? Is there any way to know what is the missing part?
Here is my code The server:
ServiceHost myHost = new ServiceHost(typeof(MyService)); WSHttpBinding binding = new WSHttpBinding { ReaderQuotas = { MaxStringContentLength = int.MaxValue, MaxArrayLength = int.MaxValue, MaxDepth = int.MaxValue, MaxBytesPerRead = int.MaxValue, MaxNameTableCharCount = int.MaxValue }, MaxReceivedMessageSize = int.MaxValue }; TimeSpan timeoutSpan = TimeSpan.FromMilliseconds(timeout); binding.CloseTimeout = timeoutSpan; binding.OpenTimeout = timeoutSpan; binding.ReceiveTimeout = timeoutSpan; binding.SendTimeout = timeoutSpan; binding.ReliableSession.InactivityTimeout = timeoutSpan; binding.MaxBufferPoolSize = int.MaxValue; //we set the security type binding.Security.Mode = SecurityMode.Message; binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName; binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None; //we set the server's certificate myHost.Credentials.ServiceCertificate.SetCertificate(StoreLocation.LocalMachine, StoreName.My, X509FindType.FindBySubjectName, ConfigurationManager.AppSettings["Hostname"]); myHost.Credentials.ClientCertificate.Authentication.CertificateValidationMode = X509CertificateValidationMode.None; //we add the endPoint(and we indicate which methods are exposed through the interface myHost.AddServiceEndpoint(services[port], binding, String.Format("http://localhost:{0}", port)); //Some services doesn't need an authentication if (!servicesWithoutAuth.Contains(services[port])) { //We set the authentifier: myHost.Credentials.UserNameAuthentication.UserNamePasswordValidationMode = UserNamePasswordValidationMode.Custom; myHost.Credentials.UserNameAuthentication.CustomUserNamePasswordValidator = new CustomUserNameValidator(); myHost.Authorization.PrincipalPermissionMode = PrincipalPermissionMode.Custom; //we set the AuthorizationPolicy List<IAuthorizationPolicy> policies = new List<IAuthorizationPolicy> { new CustomAuthorizationPolicy() }; myHost.Authorization.ExternalAuthorizationPolicies = policies.AsReadOnly(); } else { //We set the authentifier: myHost.Credentials.UserNameAuthentication.UserNamePasswordValidationMode = UserNamePasswordValidationMode.Custom; myHost.Credentials.UserNameAuthentication.CustomUserNamePasswordValidator = new NoUserNamePasswordValidator(); } //We bypass the certificate verification(our certificate is only self signed) //HACK Only to desactivate the SSL check: ServicePointManager.ServerCertificateValidationCallback += ValidateCertificate; //HACK: Remove when debug finished private static bool ValidateCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslpolicyerrors) { return true; } My client side:
