title: Replace custom authentication by WSO2 Identity Server?
body: <p>Just want to get the idea if I am looking into the right direction.
  We have the simple PHP application which do authenticate users by their name and password. So we do just md5 (of password) comparison.
  I am looking if we can replace this custom authentication by WSO Identity Server?
  But I am stuck in the terminology :(
  I were able to run WSO2 Identity Server. But what to do next? How to solve our simple task?
  Should I create <a href="https://docs.wso2.com/display/IS500/Working+with+the+Service+Provider" rel="nofollow">Service Provide</a> or <a href="https://docs.wso2.com/display/IS500/Working+with+the+Identity+Provider" rel="nofollow">Identity Provider</a> ? Or should I use Resident one?
  Moreover how should I configure them?</p>
  
  <ul>
  <li>Configure Claims (Do I need this?)</li>
  <li>Configure just-in-time provisioning (Do I need this?)</li>
  <li>Configure outbound provisioning connectors (Do I need this?)</li>
  </ul>
