what is the entry in the "crypt_default" two OSes /etc/auth.conf files?

I suspect the FreeBSD 4.8 is defaulting to MD5 encyption and the
FreeBSD 4.7 is knowledgable about DES encyption. MD5 passwords are
obvious because they start with "$1$" and they are longer than
DES encrypted passwords.

Sounds like you are re-implementing YP/NIS (see: man 8 yp).
