ncftpd_authd
If you have some sort of special requirement to authenticate users that
isn't served by the standard methods, you can have an external process
authenticate user logins. Setting the ncftpd_authd option
will require NcFTPd to send messages to this process to do the logins.
Odds are very slim you will need this option. If you do, see the
additional
documentation
for it.
Examples:
ncftpd_authd=localhost:721
ncftpd_authd=localhost:721;2
#ncftpd_authd= (commented out)
Recommendation:
#ncftpd_authd= (commented out)
