Problem with a simple Wcf service authentication

Question

 

Hello everybody,

I have developp a Wcf sample project.

This sample works fine alone but when I want to add authentication to it, it fails.

I have set the diagnostic trace for this Wcf service but the messages I get are only :"Fail to open System.ServiceModel.ServiceHost", "System.ServiceModel.ServiceHost has generated errors" and "An error System.ServiceModel.ServiceHost has appened.

I have been based on a simple example I found on the net and I think I have reproduced it correctly.

Here is the web.config file for my Wcf service :

<?xml version="1.0" encoding="utf-8"?>
<configuration>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>

Here is the App.config for my client application :

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="DefaultBinding_IService1">
          <security mode="TransportCredentialOnly">
            <transport clientCredentialType="Basic"/>
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>

      <endpoint address="http://localhost/TestServiceWCF/Service1.svc"
                binding="basicHttpBinding" bindingConfiguration="DefaultBinding_IService1"
                contract="ServiceReference1.IService1"
                name="ServiceReference1" />
    </client>

  </system.serviceModel>

</configuration>

Here is the UserAuthentication.cs :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ServiceModel;
using System.IdentityModel.Selectors;

namespace WcfService1
//namespace Service
{
    public class UserAuthentication : UserNamePasswordValidator
    {
        public override void Validate(string userName, string password)
        {
            try
            {
                if (userName == "test" && password == "test123")
                {
                    Console.WriteLine("Authentic User");
                }
            }
            catch (Exception ex)
            {
                throw new FaultException("Unknown Username or Incorrect Password");
            }
        }
    }
}

And here is my call to the Wcf service :

 ServiceReference1.Service1Client serviceProxy = new ServiceReference1.Service1Client();
                serviceProxy.ClientCredentials.UserName.UserName = "test";
                serviceProxy.ClientCredentials.UserName.Password = "test123";

                string sReturned = serviceProxy.GetData(14);

Thank you very much in advance.
