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.
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.....

What is the fqdn for the host you are looking for?
