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.

does not map into domain 'localdomain'
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.
I think you need to be a bit more specific in your replies.
Are the client and the server both Fedora systems, or at least Linux? Mine are
now. I was using a NAS but I don't have full
root privileges.
In both cases the "Domain" line /etc/idmapd.conf are commented out. The line starts with
"#".
So on the server.....
