I've read this the first time I tried and decided not to go with it.
The manual says:
"If you plan to use a FreeBSD system to serve non-FreeBSD
clients that have no support for password shadowing (which is
most of them), you will have to disable the password shadowing
entirely by uncommenting the UNSECURE=True entry in
 /var/yp/Makefile."

Linux certainly uses password shadowing, and I can see in my debian
server maps passwd.byname and shadow.byname files
If I perform ypcat passwd.byname from a client I get the standard passwd
file with no passwords (exactly like /etc/passwd)
The encrypted passwords are in the shadow.byname map.

Now, if I understand correctly, the above solution would put the
passwords in the passwd.byname map, thus making the system less secure,
where in fact I should be able to make FreeBSD export a shadow.byname
map that would be compatible with Linux.
Am I missing something here / are my assumptions wrong?
