I have implemented a similar setup using vsftpd from the ports. It works
well for secure ftp when used with the filezilla client. You can limit the
ftp command in the vsftpd configuration file so users cannot get out of
their home directories, which chroots them there. You do need to add one
thing to the accounts, which is to change their home directory in
/etc/passwd adding an additional dot. For instance if a users home
directory is:
/home/user
You'd need to change it to:
/home/./user
vsftpd is well documented and relatively easy to get setup and running.
