How WCF client connect to WSF/php service with useUsernameToken

I try to use WCF client connect WSDL generated + useUsernameToken service sample

if binding like this

            <wsHttpBinding>


                <binding >


                    <security mode="Message">


                        <message clientCredentialType="UserName" negotiateServiceCredential="true" />


                    </security>


                </binding>


            </wsHttpBinding>

--> error: missing operation

if negotiateServiceCredential="false"

-->error: The service certificate is not provided for target 'http://localhost:8080/UAR/samples/wsdl_generation/doclit_service.php'. Specify a service certificate in ClientCredentials.

additional information: the php client work well.

So, do wsf/php handle negotiate operations from clients?

please give a guide/example for WCF client connect to WSF/php service with useUsernameToken,

Thanks
