Right, but on recent kernels, the client doesn't use rpc.idmapd, it uses
"nfsidmap". The fact that rpc.idmapd isn't running doesn't really tell us
anything.
"all users and groups in an NFS mounted filesystem are mapped to "nobody" even
though the names and
numeric IDs are the same on the server and client"
So, I don't know why we're going down this path.

Right, that log entry indicates that idmap is being used on his system. That
might mean that the server doesn't support NFSv4 without idmap. Or it might
mean the client was configured to enable idmapping.
Without knowing which, we don't really know the right thing to do, except to
set the client's domain to match the servers, so that idmapping works as
expected.
If I could find any way to set the client's domain name, I would. Nothing I try
has any effect on the domain name.
When I try to set a FQDN with hostnamectl, then "hostnamectl" (with no arguments) shows that FQDN as the static
hostname, but "hostname --fqdn" responds with "hostname: Name or service not known", and "mount -t nfs
..." causes the various "... does not map into domain 'localdomain'" messages to be logged.
With a test system following those first two statement, I've go no problems.
I would imagine that idmapping is disabled on your client (and supported by
your server).
Check the value of /sys/module/nfsd/parameters/nfs4_disable_idmapping on your
NFS server, if it's Linux. And check the value of
/sys/module/nfs/parameters/nfs4_disable_idmapping on the client.
On the server:
[plugh-3g ~]# cat /sys/module/nfsd/parameters/nfs4_disable_idmapping
