Как настроить беспарольный доступ к FTP?

Здравствуйте. На Debian Jessie установил ProFTPd и настроил анонимный доступ: в браузере набираю - всё заходит как и куда нужно: без запроса пароля. Подскажите, пожалуйста, как настроить ProFTPd так, чтобы можно было заходить беспарольно и для другого пользователя, вводя в браузере, например, ftp://torrents@ ?

В системе я уже создал пользователя и задал ему пароль:
useradd torrents -d /home/torrents/transmission/downloads -m -U -s /bin/false
passwd torrents

При подключении, указав пароль - заходит в домашнюю директорию созданного пользователя.

Если же я удаляю пароль у пользователя:
passwd torrents -d

то пароль всё равно запрашивается, но подключения не происходит.

В чём может быть дело? В Debian Wheezy этот трюк срабатывал, а в Jessie что-то не подключается.

На всякий случай прилагаю свой файл /etc/proftpd/proftpd.conf:
