In a Fedora 35 VM, all users and groups in an NFS mounted filesystem are mapped to

I have no nfs-idmapd service running. This same setup is running fine on a
CentOS 8 VM. I didn't have to do anything special to make this work in CentOS
8. What am I missing here in a Fedora 35 installed with default configuration
in a QEMU/KVM virtual machine?
Where does Fedora get its domain name? When I type "hostname --fqdn" I get "hostname: Name or
service not known". The CentOS 8 VM apparently gets its domain name from the /etc/hostname file, which
contains "cent9-vm.local". This does not appear to work in Fedora 35.
What do you get when you type "hostnamectl"?
On one of my VM's
[egreshko@f35ser ~]$ hostname --fqdn
f35ser.greshko.com
[egreshko@f35ser ~]$ hostnamectl

From the man page....
domainname - show or set the system's NIS/YP domain name
So that comman is irrelevant.

If I put a fqdn in /etc/hostname, that will show up as the static hostname, but
"domainname" still returns "(none)" and everything else is the same.
Rather than manipulating files which may no longer be used.....
As root: hostnamectl name.domain.com
Example: For the host that I mentioned I used "hostnamectl f35ser.greshko.com"
Then hostname --fqdn returns the desired info.
FWIW, I created a user on that system with the same UID and GID of a user on a
NAS. Which I think is similar to your setup.
No change:
[fedora ~]# hostnamectl hostname fedora.local
[fedora ~]# hostnamectl

A reboot after setting the hostname yields the same result. And, it's not because of
anything special about a ".local" domain. Nothing I put in there causes a FQDN
to be set.
