對於一個應用程序，我需要一個WCF服務的SSL證書，WCF SSL證書使用企業CA
所以我們安裝了它。如果我使用瀏覽器通過https瀏覽器訪問互聯網瀏覽器，我沒有任何問題，也沒有警告，沒有任何內容，所以我想這個證書被認爲對Windows有效。
的問題是，當我試圖連接到我的WCF的服務器，我得到這個錯誤：
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.
什麼可能是錯誤的？我怎麼知道鏈條的哪一部分是無效的？有什麼方法可以知道缺失的部分是什麼？
這裏是我的代碼 服務器：
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;
}

string remoteAddress = String.Format("{0}://{1}:{2}", Tools.GetDescription(accessInfo.ServiceHost.Protocol), accessInfo.ServiceHost.HostName, accessInfo.PortNumber);
// HACK: binding depends on protocol -> switch over accessInfo.ServiceHost.Protocol
// avoid seralization/deserialization problems with large XML's
