When using the Paged Results Control, according to RFC2696 (Section 3), the
server must sent the control with an empty cookie, if there are no more values
to return (i.e. the last page of results was sent). At the moment however slapd
doesn't sent the control at all with the last page, this confuses some clients
e.g. nss_ldap.
