+1; the idmapdomains have to be the same and the users accessing the
nfs share have to be "known" on the server either in its /etc/passwd
or through nis-nisplus-ldap.

Also, an nfsv4 mount invocation is different from a previous nfs
version's mount invocation.

If you are exporting
/path/to/shareddir
from nfsserver, you have to mount
nfsserver:/ /path/to/mountpoint
on your client

You may have to export with
fsid=0
or
fsid=root
but it may be assumed if there isn't a directory exported at a higher
level, but I have not tested it is assumed without.
