WCFTestClient The HTTP request is unauthorized wit

Question

I've created one WCF service and deployed it on Server. When I browse this service it gives me positive response with ?wsdl URL. Now I'm trying to test the service through WCF Test client. It shows proper metadata. But when I try to invoke any of the method from the service it shows me an exception... here are the erro details with stack trace..

The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Negotiate,NTLM'.

Server stack trace:

at
System.ServiceModel.Channels.HttpChannelUtilities.ValidateAuthentication(HttpWebRequest request, HttpWebResponse response, WebException responseException, HttpChannelFactory factory)

Answer 1

I had a similar problem and tried everything suggested above. Then I tried changing the clientCreditialType to Basic and everything worked fine.

<basicHttpBinding>
    <binding name="BINDINGNAMEGOESHERE" >
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Basic"></transport>
      </security>
    </binding>
  </basicHttpBinding>

Answer 2

Another possible solution to this error that I found. Might not have answered OP's exact question but may help others who stumble across this error message.

I was creating my Client in code using WebHttpBinding, in order to replicate the following line:

<security mode="TransportCredentialOnly">
  <transport clientCredentialType="Windows" proxyCredentialType="Windows" />
</security>

I had to do:

var binding = new WebHttpBinding(WebHttpSecurityMode.TransportCredentialOnly);
                binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;
                binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.Windows;

as well as setting proxy.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;

Answer 3

Here's what I had to do to get this working. This means:

1. Custom UserNamePasswordValidator (no need for a Windows account, SQLServer or ActiveDirectory -- your UserNamePasswordValidator could have username & password hardcoded, or read it from a text file, MySQL or whatever).
2. https
3. IIS7
4. .net 4.0

My site is managed through DotNetPanel. It has 3 security options for virtual directories:

1. Allow Anonymous Access
2. Enable Basic Authentication
3. Enable Integrated Windows Authentication

Only "Allow Anonymous Access" is needed (although, that, by itself wasn't enough).

Setting

proxy.ClientCredentials.Windows.AllowedImpersonationLevel =  System.Security.Principal.TokenImpersonationLevel.Impersonation;

Didn't make a difference in my case.

However, using this binding worked:

      <security mode="TransportWithMessageCredential">
        <transport clientCredentialType="Windows" />
        <message clientCredentialType="UserName" />
      </security>
