[gollem] gollem with Hordeauth login hang

[=?big5?b?sWmofaTl?=]

Hi there:
Horde 3.0 cvs + gollem 1.0 cvs
ENV: http://210.241.49.68/horde.beta/test.php

Gollem login with hordeauth works great for me,but since serveral months ago it
doesn't.

Here is my backend.php,and my ftp server is wu-ftpd wu-2.6.2 tarball version
============================================================================
// This backend uses Horde credentials to automatically log in.
$backends['hordeftp'] = array(
    'name' => 'WWW Server',
    'driver' => 'ftp',
    'preferred' => '',
    'hordeauth' => true,
    'params' => array(
        // The hostname/IP Address of the FTP server
        'hostspec' => 'www.tmv.gov.tw',
        // The port number of the FTP server
        'port' => 21,
        // Use passive mode?
        'pasv' => false
    ),
    'attributes' => array('type', 'name', 'download', 'modified', 'size', 'permi
ssion', 'owner', 'group')
);

Here is conf.php
===============================================================================
/* CONFIG START. DO NOT CHANGE ANYTHING IN OR AFTER THIS LINE. */
// $Horde: gollem/config/conf.xml,v 1.4 2004/04/02 18:41:18 chuck Exp $
$conf['manager']['date_format'] = '%x';
$conf['menu']['apps'] = array();
$conf['backend']['backend_list'] = 'shown';
$conf['backend']['change_server'] = false;
$conf['backend']['change_port'] = false;

And here is what wu-ftpd server says in /var/log/messages:
