I have real issues understanding FreeBSD's ftpd!

Man page "ftpusers(5)" states, that an entry "username allow" will allow access
to ftpd. But every user listed in /etc/ftpusers is denied access, no matter
whether there is "allow" appended to the entry or not! This is strange.
Whenever I delete a user's name from that file I wish to have access to the
ftpd service, that user can login - but addig the users even as "username
allow" (no * in the file, nothing else but the initial users names) access is
denied.

I managed so far to start the ftpd via inetd - the service running
from /etc/rc.conf is still impossible. But operations, not even a simple "ls",
are possible since the service dies ...

Either I'm some kind of dull and do not understand this brillant peice of
software, or there is something really fishy.

regards and nice weekend,
