WCF error: The caller was not authenticated by the service

I am trying to access my WCF service on a server from my client console application for testing. I am getting the following error:

The caller was not authenticated by the service

I am using wsHttpBinding. I'm not sure what kind of authentication the service is expecting?



<behaviors>
  <serviceBehaviors>
    <behavior name="MyTrakerService.MyTrakerServiceBehavior">
      <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
      <serviceMetadata httpGetEnabled="true"/>
      <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
      <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

Update It works if I change my binding to <endpoint "basicHttpBinding" ... /> (from wsHttpBinding) on the IIS 7.0 hosted, windows 2008 server

If you use basicHttpBinding, configure the endpoint security to "None" and transport clientCredintialType to "None."

<bindings>
    <basicHttpBinding>
        <binding name="MyBasicHttpBinding">
            <security mode="None">
                <transport clientCredentialType="None" />
            </security>
        </binding>
    </basicHttpBinding>
</bindings>
<services>
    <service behaviorConfiguration="MyServiceBehavior" name="MyService">
        <endpoint 
            binding="basicHttpBinding" 
            bindingConfiguration="MyBasicHttpBinding"
            name="basicEndPoint"    
            contract="IMyService" 
        />
</service>

Also, make sure the directory Authentication Methods in IIS to Enable Anonymous access

I got it.

If you want to use wshttpbinding, u need to add windows credentials as below.

svc.ClientCredentials.Windows.ClientCredential.UserName = "abc";
svc.ClientCredentials.Windows.ClientCredential.Password = "xxx";

thanks

Have you tried using basicHttpBinding instead of wsHttpBinding? If do not need any authentication and the Ws-* implementations are not required, you'd probably be better off with plain old basicHttpBinding. WsHttpBinding implements WS-Security for message security and authentication.

I also had the same problem in wsHtppBinding. And I just had to add security mode pointing to none, that solved my problem and no need to switch to basicHttpBinding. Check Here and check how to disable WCF security. Check the below config change for reference:

<wsHttpBinding>
    <binding name="soapBinding">
        <security mode="None">
            <transport clientCredentialType="None" />
            <message establishSecurityContext="false" />
        </security>
    </binding>
</wsHttpBinding>
