title: WCF Security for Web, Windows and mobile clients
body: <p>I am building an application that will have web, windows and mobile (iPhone) client, I want to use WCF to implement the service layer and not being familiar with WCF I am a little confused when it comes to security, authentication and authorization.  </p>
  
  <p>What I would typically like is to re-use as much of the ASP.Net membership components as possible to save me time writing that code as it is tedious and repetitive.  Is this a good approach and what alternatives are there?</p>
  
  <p>Can anyone give me guidance as to how best achieve what I am looking for?</p>
