title: Oracle: Restricting "Other Users" visible
body: <p>I'm a novice in administration and trying to improve security on our Oracle database.</p>
  
  <p>Currently, a non-privileged user can see a list of all other users in SQL Developer by expanding the "Other Users" icon, in the database navigation tree.</p>
  
  <p>How does one restrict privileges so users will only see those (other) users that have granted them a privilege on some object (rather than all users, whether privilege has been granted or not).</p>
  
  <p>Thanks.</p>
