title: How to replace the Camunda Authentication with OAuth2 provider
body: <p>I was trying to write OAuth2 plugin for Camunda , I followed the interface </p>
  
  <blockquote>
    <p>org.camunda.bpm.engine.impl.identity.ReadOnlyIdentityProvider</p>
  </blockquote>
  
  <p>and I followed the process for LDAP, to replace the auth and get user list from Oauth2 provider and also the groups. </p>

  <p>Is there any implantation is there for Camunda OAuth2 ?</p>
