[OpenAFS] AFS client over NIS

[Hongliang Gai]

Hi All,
I'm trying to convert existing Linux users(NIS) to AFS users.
Should I disable NIS client on every local machine on which AFS users
will login? (suppose NIS server and AFS server are running in same
machine)
or if NIS client and AFS client can be running in the same local
machine,how to set up entries in local /etc/passwd , /etc/shadow and
/etc/group files?( here "local" means machines other than AFS and NIS
server).

Thanks in advance,
