title: Send Authenticated User To WCF Application
body: <p>I have 2 applications; one is a ASP.NET 3.5 Ajax Application (Client) and the other is a WCF Web Application (BackEnd).</p>
  
  <p>The applications are deployed in a separate Windows Server 2008 over IIS 7.  The backend application has the net.tcp and http bindings enabled; some services are exposed under the netTcpBinding and other services are exposed under basicHttpBinding; the bindings not have configured any security.</p>
  
  <p>The Client application use FormsAuthentication for authenticate users.  All of the services under netTcpBinding are consumed in the client application. In the backend I need to know which user calls the service to make some audit task.  Is this possible?</p>
