ServiceSecurityContext.Current is null in WCF - wcf

Question

I'm trying to retrieve the logged in windows user in a WCF service.
I've tried using ServiceSecurityContext but Current is always null.
ServiceSecurityContext.Current.WindowsIdentity.Name
I've also tried using OperationContext. In this case ServiceSecurityContext returns as null.
OperationContext.Current.ServiceSecurityContext.PrimaryIdentity.Name
Here's my web.config:
<bindings>
<basicHttpBinding>
<binding name="HttpWindowsBinding">
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Windows" />
</security>
</binding>
</basicHttpBinding>
</bindings>
also
<authentication mode="Windows"/>
Can anyone see what I'm doing wrong?
UPDATE:
I abandoned trying to get ServiceSecurityContext to work. In the end, I found a solution by setting aspNetCompatibilityEnabled="true".
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" />
I also added the following attribute to my service class:
[System.ServiceModel.Activation.AspNetCompatibilityRequirements(RequirementsMode = System.ServiceModel.Activation.AspNetCompatibilityRequirementsMode.Required)]
This allowed me to retrieve the windows user with:
HttpContext.Current.User.Identity.Name

I got the same error and managed to solved it, you need not to use basichttpBinding. bellow is my config:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="MSADC">
<security mode ="Message">
<transport clientCredentialType="Windows" />
<message establishSecurityContext="true" />
</security>
</binding>
</wsHttpBinding>
