27 *  <li>If the user has not logged in, then reply with 530</li>
28 *  <li>If the required pathname parameter is missing, then reply with 501</li>
29 *  <li>If the pathname parameter does not specify an existing, empty directory, then reply with 550</li>
30 *  <li>Otherwise, reply with 250</li>
31 * </ol>
32 * The supplied pathname may be absolute or relative to the current directory.
