================================================================================
This port relies on a number of configuration files in /usr/local/etc.
At the very least, create a ftpusers file with the usernams of users you don't
want to connect (root, toor, etc.). This will allow non-listed users to log in.
Copying /etc/ftpusers to /usr/local/etc/ftpusers should be sufficient.

See the man files for more information. The man- and configuration files for
FreeBSD's built-in ftpd can also be of use as examples/additional info.
