proftpd на centos 7 с помощью proftp-mysql: пользователи могут входить в систему / выгружать файлы, но они не могут получать файлы или CWD

Я не могу найти никого, у кого есть эта странная проблема: Пользователи ftp могут загружать файлы, но не могут их получить.

Пожалуйста, дайте мне ключ к решению этой проблемы. Спасибо

"ftpuser1" - это пользователь, определенный в таблице proftp-mysql с помощью home: / srv / ftp / users / ftpuser1

когда «ftpuser1» запускает сеанс ftp, он правильно подключается поэтому он загружает файл и создает каталоги в / srv / ftp / users / ftpuser1 но когда он пытается cwd или получить файл, он получает 500 ошибок, и кажется, что он пытается читать от виртуального пользователя /

ftpuser1 отображается на uid / gid 2001/2001 вот все права доступа к каталогам

# ls -aldn /srv /srv/ftp /srv/ftp/users /srv/ftp/users/ftpuser1 
/srv/ftp/users/ftpuser1/directory1/
drwxr-xr-x. 3    0    0 16 May 23  2016 /srv
drwxr-xr-x. 3    0    0 18 May 23  2016 /srv/ftp
drwxr-xr-x. 6   99   99 67 Sep  9 08:03 /srv/ftp/users
drwx------. 3 2001 2001 23 Sep  9 08:04 /srv/ftp/users/ftpuser1
drwxr-xr-x. 2 2001 2001  6 Sep  9 08:03 /srv/ftp/users/ftpuser1/directory1/

кроме того с параметром -Z кажется, что se linux флаги в порядке

# ls -aldnZ /srv /srv/ftp /srv/ftp/users /srv/ftp/users/ftpuser1 
/srv/ftp/users/ftpuser1/directory1/
drwxr-xr-x.    0    0 system_u:object_r:var_t:s0       /srv
drwxr-xr-x.    0    0 unconfined_u:object_r:public_content_t:s0 /srv/ftp
drwxr-xr-x.   99   99 unconfined_u:object_r:public_content_rw_t:s0 /srv/ftp/users
drwx------. 2001 2001 unconfined_u:object_r:public_content_rw_t:s0 /srv/ftp/users/ftpuser1
drwxr-xr-x. 2001 2001 unconfined_u:object_r:public_content_rw_t:s0 /srv/ftp/users/ftpuser1/directory1/

Я отключил selinux и ничего не изменилось Я не нашел ничего в журналах proftpd или журнале аудита

Я использую эти пакеты в журнале centos 7
