Sure. In my case, there is separate master.passwd and group files in
/var/yp directory. All regular user accounts (typically with uid=>1000)
resides here. Same for groups. In local /etc/master.passwd resides only
system accounts and some accounts for applications.
This works for 4.x, 5.x, 6.x without problems. I even have Linux
clients authorising against FreeBSD NIS servers.
(Some modifications to /var/yp/Makefile needed).
So, from interoperability and security points of view,
much better to separate system accounts and keep them localy.
