proftp设置磁盘限额后的用户无法登陆了,到底是什么问题啊？？？？？？

1、不设置磁盘限额的话所有用户登录一切正常。
2、只有设置磁盘限额的用户不能登陆而未设置的用户登陆一切正常，把磁盘限额去掉也能正常登录。

建立的mysql 数据表
CREATE TABLE quotalimits (
name VARCHAR(30),
quota_type ENUM("user", "group", "class", "all") NOT NULL,
per_session ENUM("false", "true") NOT NULL,
limit_type ENUM("soft", "hard") NOT NULL,
bytes_in_avail FLOAT NOT NULL,
bytes_out_avail FLOAT NOT NULL,
bytes_xfer_avail FLOAT NOT NULL,
files_in_avail INT UNSIGNED NOT NULL,
files_out_avail INT UNSIGNED NOT NULL,
files_xfer_avail INT UNSIGNED NOT NULL
);

CREATE TABLE quotatallies (
name VARCHAR(30) NOT NULL,
quota_type ENUM("user", "group", "class", "all") NOT NULL,
bytes_in_used FLOAT NOT NULL,
bytes_out_used FLOAT NOT NULL,
bytes_xfer_used FLOAT NOT NULL,
files_in_used INT UNSIGNED NOT NULL,
files_out_used INT UNSIGNED NOT NULL,
files_xfer_used INT UNSIGNED NOT NULL
);

quotatallies 记录了用户当前的磁盘使用情况，由程序自动记录。
quotalimits 设置磁盘限额，表中一些字段的含意如下：
quota_type 磁盘限额的鉴别
bytes_in_avail 上传最大字节数，就是FTP用户空间容量
bytes_out_avail 下载最大字节数
bytes_xfer_avail 总共可传输的文件的最大字节数(上传和下载流量)
files_in_avail 总共能上传文件的数目
files_out_avail 能从服务器上下载文件的总数目
files_xfer_avail 总共可传输文件的数目(上传和下载）
