title: AuthenticationSupport service missing after installing S3 connector
body: <p>I installed S3 Connector for AEM (COM.ADOBE.GRANITE.OAK.S3CONNECTOR) through the package share, and now my AEM instance is bricked.</p>
  
  <p>Whenever I go to localhost:4502, I get a page saying:</p>
  
  <pre><code>HTTP ERROR: 503
  
  Problem accessing /. Reason:
  
      AuthenticationSupport service missing. Cannot authenticate request.

  <p>How can I fix/prevent this error?</p>
  
  <p>EDIT: I tried installing this package again on another instance I had, and after a short time, this error happened automatically.  The first time I had reset my instance. This time, I just let it sit after installing it, since I had heard to do so from somewhere.</p>
