We have RHL9, RHEL3, RHEL4, FC1, FC3, FC4, HP-UX and Solaris boxes at
$WORKPLACE all using the same NIS. The way we do it is to use NIS only
for regular user accounts, and we use UIDs >= 1000 for this. We use
separate files /etc/passwd.nis and /etc/group.nis on the NIS master
server (HP-UX) rather than its own /etc/passwd and /etc/group to create
the NIS databases. This is done by modifying the Makefile on the NIS
master server.

So each client uses its own UIDs for system accounts (< UID 1000) and
NIS for user accounts. Works fine.

Paul.
