NIS/YP on RH7.1

Since many of us manage quite large networks I believe it appropriate to ask
question about NIS/YP here. I've used RH6.2 and managed NIS quite
successfully, but now I am at a loss. The software in RH7.1 is a bit
different from that of 6.2 and seems to behave differently as well.
My basic problem is I have 8 seperate cluster networks that are also
connected together by a ninth network (dubbed .treenet), a basic tree
topology. A seperate server on the interconnecting network is the NIS
master and is the only machine where I directly edit user configurations.
Now my 8 other servers are NIS slave servers and serve NIS requests to their
respective cluster networks. All of this is in one domain, say . . .
cluster.nis. Now as I add, delete, and modify user accounts on the master
machine the changes do not progress to the slave servers. I've tried to run
/usr/lib/yp/ypinit -m on the master and /usr/lib/yp/ypinit -s master.treenet
on the slaves, but the slaves give me an error: "Can't enumerate maps from
ga. Please check that it is running." I cannot get these maps to migrate,
with the exception of running the /usr/lib/yp/ypxfr_1perday and such
scripts, but this is not convenient as I wish these changes to migrate NOW!
This all worked in RH6.2, but it does not seem to work in RH7.1.
Also, ypbind is working, I have cluster nodes looking to their server (a NIS
slave server) and the slave servers look to themselves. This sounds logical
to me since the slaves will update when the master pushes new maps.
I've also read the NIS/YP HOWTO, but nothing seems to work. Maybe some of
you know the answers or can give me pointers. This is the only thing
keeping me from opening these machines to users.
