title: How to integrate login module with external user system exposed as RESTful API in AEM 6.0?
body: <p>I'm researching how to integrate or custom login module in order to work with external user system exposed as RESTful API.</p>
  
  <p>I saw AuthenticationHandler interface but it seems that it only extracts credential from user request. Then build and send the AuthenticationInfo object to CRX login module for authentication &amp; authorization.
  I stuck in at this point.</p>
  
  <p>Do anyone know a solution for this one in AEM 6.0 ? </p>
  
  <p>thanks and appreciate your help.</p>
