Control Users ability to see each other

Question of the Day: Can I segment the registered users of the CMA from "seeing each other" in the Active Directory?

Answer; An administrator can enable ACL, Access Control Lists on the Active Directory to limit the ability from one user to "see" another user. This will limit the ability to search for an individual user but will not limit the ability one user to call another if they happen to know the IP address, E.164, or Annex O dial string.
