[Proftpd-user] create a ftp-only account

[Jun L. <lx...@fs...>]

Hi, all,

I used to set default shell to /dev/null to limit an account as
ftp-only. Is it possible not to touch /etc/passwd and /etc/group, and to
create an account only valid for proftpd?

I tried to read SQL, but somehow I don't really understand the mechanism
of SQL authorization. I need a simple but secure way to accomplish
this. :)

Thanks,

/Jun
