You can hack the sources for yppasswd and take it out, that's what I did.

samba runs as root anyway, and I changed the program to yppasswd.hack
and chown'ed it 0700 for root only access.

There's a program called NISGINA, which has a samba password syncing 
tool. So I've created a script on each samba server which act as slaves too,
so when the slave receives a password change it sync's via unix's nis setup
and also sync's the samba password on all domain servers too.

Basically I have three domain servers all running nis and I can change my
password on one of the domains and it sync's them all on every domain, and 
even on the unix system.
