As u can see i've decided to put my users in jail.
Their home directory is now /home/hosting/user
These users must have ftp capabilities but as I speak their login is rejected by the Proftpd server... (SSH works well).
Instead my default login niels (home/niels) is working great.
My /etc/passwd for example :
where /bin/chroot is a little script that execute the chroot command.
If u know how i can configure ProFTPd to work with chrooted users and niels, you'll be welcome
NB : myweb isn't in ftp_users
