Question

我使用wsDualHttpBinding构建了一个简单的WCF服务。它在本地端工作正常，但是当我在不同的服务器上发布服务并尝试在WPF项目中使用该服务时，它会引发错误。

错误：

System.ServiceModel.SecurityNegotiationException     "The caller was not authenticated by the service."

的InnerException：

System.ServiceModel.FaultException        "The caller was not authenticated by the service." 

服务器配置：

<system.serviceModel>
    <services>
      <service name="VetChat.Service.VetChatService" behaviorConfiguration="wsDualHttpBinding.SampleServiceBehavior">
        <!-- Service Endpoints -->
        <host>
          <baseAddresses>
            <add baseAddress="http://service.softprodigy.com:8090/VetChatService.svc"/>
          </baseAddresses>
        </host>
        <endpoint address="" binding="wsDualHttpBinding" contract="VetChat.Service.IVetChatService">

客户端配置：

<system.serviceModel>
    <bindings>
      <wsDualHttpBinding>
        <binding name="WSDualHttpBinding_IVetChatService" />
      </wsDualHttpBinding>
    </bindings>

    <client>

    </behaviors>

接口：

[ServiceContract(CallbackContract = typeof(ICallback), SessionMode = SessionMode.Required)]
    public interface IVetChatService
    {
       [OperationContract(IsOneWay = true)]
        void DoWork();
    }

    public interface ICallback
    {
        [OperationContract(IsOneWay = true)]
        void Notify(string value);
    }

接口实施：

public class VetChatService : IVetChatService
    {
        public void DoWork()
        {
            //Thread.Sleep(5000);
            OperationContext.Current.GetCallbackChannel<ICallback>().Notify("Hello");

        }
    }

Validte用户名密码服务类：

namespace VetChat.Service
{
    class UserNamePassValidator :
          System.IdentityModel.Selectors.UserNamePasswordValidator
    {
        public override void Validate(string userName, string password)
        {
            if (userName == null || password == null)
            {
                throw new ArgumentNullException();
            }

            if (!(userName == UserName && password == Password))
            {
                //throw new FaultException("Incorrect Username or Password");
            }
        }
    }
    public class Service
    {
    }
}

通话方式：

    InstanceContext instanceContext = new InstanceContext(new SampleServiceCallback());

    ServiceReference1.VetChatServiceClient sampleServiceClient = new ServiceReference1.VetChatServiceClient(instanceContext);


    sampleServiceClient.ClientCredentials.ClientCertificate.SetCertificate(
           StoreLocation.CurrentUser,
           StoreName.TrustedPeople,
           X509FindType.FindBySubjectName,
           "MyName");
    sampleServiceClient.ClientCredentials.UserName.UserName = UserName;
    sampleServiceClient.ClientCredentials.UserName.Password = Password;
    //sampleServiceClient.Open();
    sampleServiceClient.DoWork();

响应回调：

public class SampleServiceCallback : ServiceReference1.IVetChatServiceCallback
    {

        #region ISampleServiceCallback Members

        public void Notify(string value)
        {
            MessageBox.Show(value);
        }

        #endregion
    }
