where can I ask user qns about nfs4?

[steve <steve@steve-ss.com>]

I want to ask a question about nfs4 keytabs and Samba 4. I've tried 
asking here, on the Samba 4 list and on the openSUSE list (which is my 
Linux distribution) but they refer me to an nfs list. I see that this 
list is only for nfs devs.

I don't want to waste your time here but my question is just this:

My nfs4 server has a service principal nfs/server.domain.name

I already use nfs4 to serve my Linux clients. I'm going to kerberize it. 
My clients already have machine and host principals. What else do they need?

1. nfs/client.domain.name
2. nfs/server.domain/name
3. neither
4. both

The Google doco is contradictory and confusing to say the least. If you 
can't help, could you point me in the right direction?

Thanks so much fr your time,
Steve
