请教：pureftpd_manager创建的用户无法登陆？

环境：CentOS5.2+MySQL + Pureftpd + pureftpd_php_manager 2.1

本人比较懒，想用web方式来管理服务器上的ftp帐户。
环境是搭建好了，数据库也创建了，能通过pureftpd_php_manager登陆。
但是在pureftpd_php_manager里创建的用户，在客户端登陆的时候提示：

C:\>ftp 192.168.80.198
Connected to 192.168.80.198.
220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------
220-You are user number 1 of 50 allowed.
220-Local time is now 21:24. Server port: 21.
220 You will be disconnected after 15 minutes of inactivity.
User (192.168.80.198none)): ftpuser_1
331 User ftpuser_1 OK. Password required
Password:
Connection closed by remote host.

输完密码后马上就返回：Connection closed by remote host.密码没有输错。
