NFS4 and nobody problems

[gauss]

I have a Heron, server, and a Heron, client. I have users foo and bar and group baz with identical numerical GIDs and UIDs on both. I'd like to mount server's /home/foo as client's /home/foo and have followed https://help.ubuntu.com/community/NFSv4Howto. I'd like to be able to "see" the same users and groups on both machines within /home/foo.

It mounts correctly but all UID's (e.g. both foo and bar) in /home/foo on client are mapped to nobody and all GID's are mapped to nogroup. This means that foo can't use /home/foo on client like it can on server. E.g.
$ ssh server fails on client with
Bad owner or permissions on /home/foo/.ssh/config which is correct since config has owner nobody and nobody has a different UID than foo.

Here's /etc/exports on server:
/srv client(ro,fsid=0,insecure,no_subtree_check,async)
/srv/foo client(rw,nohide,insecure,no_subtree_check,async) Also /etc/fstab binds /srv/foo to /home/foo on server.

Here's /etc/fstab on client:
server:/foo /home/foo nfs4 proto=tcp,soft,defaults 0 0

Is there any way I can get what I want with NFS: to be able to view the same UIDs and GIDs on client as I see on server so that foo on both boxes can "act the same"?

Thanks for any insight you can provide.

This seems to work. For server's /etc/exports:
/home/foo client(rw,no_subtree_check,sync)


For client's /etc/fstab:
server:/home/foo /home/foo nfs defaults,soft 0 0
