在 OpenLDAP 中分页 ldap_search 以绕过大小限制？

$result = ldap_search($ldapconn, $base_dn, $filter, $attributes, 0, 1000);

$pageSize = 1000;
$cookie = '';
$results = [];

do {
    ldap_control_paged_result(
        $ldapconn,
        $pageSize,
        true,
        $cookie
    );

    $result = ldap_search($ldapconn, $base_dn, $filter, $attributes);

    if (ldap_count_entries($ldapconn, $result) > 0) {
        $entries = ldap_get_entries($ldapconn, $result);

        foreach ($entries as $entry) {
            $results[] = $entry;
        }
    }

    ldap_control_paged_result_response(
        $ldapconn,
        $result,
        $cookie
    );
} while (!empty($cookie));
