title: Any sample with WIF + WCF for login / password validation?
body: <p>There are many WIF examples for Asp.Net. However samples with WCFServiceLibrary are scarce. </p>
  
  <p>Does anyone have an example with user credential of type username password? </p>
  
  <p>I'd like to verify them via a CustomUserNameValidator which works on a view linked to my database.</p>
  
  <p>Thanks</p>
