.net – WCF error: The caller was not authenticated by the service

netSecuritywcfwcf-binding

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
