title: Session Management using keycloak
body: <p>My legacy application needs to delegate user authentication to 'keycloak' which is a SSO provider. I have a couple of questions</p>
  
  <ol>
  <li>What happens to my legacy session-management? Do I still need to maintain it? </li>
  <li>Can 'keycloak' act as my session management server or is it only an authentication system.</li>
  </ol>
