title: Zookeeper acl to allow any authenticated user
body: <p>I want to use custom login module on zookeeper and then allow any authenticated user who has the ability to log in to do any action on the znode. How would I go about that?</p>
  
  <pre><code>setAcl /znode auth:crdwa
  </code></pre>
  
  <p>is not a valid acl assignment. If there is no other way than to specify usernames, can I at least set the acl without specifying the password? Something like:</p>
  
  <pre><code>setAcl /znode auth:user:crdwa
  </code></pre>
  
  <p>I want the authentication to be taken care of using the custom login module.</p>
