Host custom WCF service with authentication within Umbraco - wcf

Question

I've created a custom WCF service within Umbraco. The service resides in the Service folder and seems to be working fine (I can call it and it responds appropriately). Now I want the users to authenticate themselves when they call the service.
To do this I've added these lines into the web.config:
<system.serviceModel>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" />
<bindings>
<webHttpBinding>
<binding name="RaceManBinding">
<security mode="None" />
</binding>
</webHttpBinding>
</bindings>
<services>
<service name="RaceManagerAdmin.RaceManDataService" behaviorConfiguration="RaceManBehavior">
<endpoint address=""
binding="webHttpBinding"
contract="System.Data.Services.IRequestHandler" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="RaceManBehavior">
<serviceCredentials>
<userNameAuthentication userNamePasswordValidationMode="MembershipProvider"
membershipProviderName="UmbracoMembershipProvider" />
</serviceCredentials>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
When my service is called it should use the Umbraco membership provider to authenticate the users.
My client specificies this by creating a network credential object, like this:
var a = new RaceEntities(new Uri("http://localhost:40406/umbraco/Webservices/RaceManDataService.svc")) { Credentials = new NetworkCredential("admin", "secret") };
When I inspect the HTTPContext.Current I don't see any authenticated users.
What am I doing wrong?

You'll need to enable ASP.Net Compatibility in order to access the identity via the HttpContext:
<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
</system.serviceModel>
The answer to this question mentions an alternate method: How to access HttpContext.Current.User.Username in WCF service
