WCF UserName clientCredentialType

Question

I have a WCF service with following configuration:

        <service behaviorConfiguration="MyServiceBehavior" name="Service1">
            <endpoint address=""
                      binding="wsHttpBinding" bindingConfiguration="MembershipBinding"
                      name="ASPmemberUserName" contract="TestWcfService.IService1" />           
        </service>
         .
         .
         .
         .
         .
        <wsHttpBinding>
            <binding name="MembershipBinding">
                <security mode="Message">
                    <message clientCredentialType="UserName" />
                </security>
            </binding>
        </wsHttpBinding>

I want to pass the username to the service proxy on client and retrieve it on the server side. I use bellow code to pass the user name to the proxy class:

Service1Client sc = new Service1Client();

sc.ClientCredentials.UserName.UserName = HttpContext.Current.User.Identity.Name;

When I try to retrieve the username on the server, the ServiceSecurityContext.Current returns null. Any ideas why it acts like this?

The problem was caused by certificate settings. Below link helped solve the issue:
