ckpasswd -d /usr/local/news/db/newsusers

[Steve Prior]

I'm trying to get authentication working with ckpasswd -d
/usr/local/news/db/newsusers, but can't
find any documentation of the format of the newsusers file or what tools might
be available to
create the encrypted passwords.  I tried making a copy of /etc/shadow and
removing the extra
fields, but it didn't work.

Can anyone give me a quick rundown of how to create a working newsusers file for
ckpasswd -d?

Thanks in advance
