WCFTestClient The HTTP request is unauthorized with client authentication scheme 'Anonymous'

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 didn't have control over the security configuration for the service I was calling into, but got the same error. I was able to fix my client as follows.

1. In the config, set up the security mode:

   <security mode="TransportCredentialOnly">   <transport clientCredentialType="Windows" proxyCredentialType="None" realm="" />   <message clientCredentialType="UserName" algorithmSuite="Default" /> </security> 

2. In the code, set the proxy class to allow impersonation (I added a reference to a service called customer):

   Customer_PortClient proxy = new Customer_PortClient(); proxy.ClientCredentials.Windows.AllowedImpersonationLevel =              System.Security.Principal.TokenImpersonationLevel.Impersonation;
