     * - "anyone" means any authenticated user, including anonymous
     * - an identifier starting with a minus sign ('-') indicates
     *   "negative rights": rights that should be taken away from
     *   matching users
     *
     * Other than the above restrictions, ACL identifiers are usually
     * IMAP usernames, but could potentially be group names as well.
     *
     * Note that negative rights override positive rights: if
     * "fred" and "-fred" are both assigned the 'w' right, the
     * user "fred" will not have the 'w' right.
