 * server be used to process the associated search or compare request, and that
 * the request should not be processed on a directory that may contain data
 * that is cached or potentially stale.  If the client includes this control in
 * a request sent to a non-authoritative server, then that server may send a
 * referral to the authoritative server, or it may simply reject the request.
