I am struggling with an issue setting up a new NFS client. We are using NFSv4.
The old NFS client is Red Hat 5 and I am replacing it with an Oracle Linux 7.3 box.
All of the NFS exporting has been done on the server side, and I am able to mound the remote directories. I'ver performed exportfs -a and restarted the nfsserver service afterwards.
The issue is, if I look at my old NFS client box, it shows all of the user:group owner as the nobody-user and nobody-group. When I mount the same share on my new NFS client, it is not mounting with the nobody-user and nobody-group owners (which is what I want). In the output below, the "old-nfsclient" has the desired behavior. Setgid is set on the "output" directory though I am not sure that factors in.
If I look at /proc/fs/nfs/exports, it shows both have the "root_squash" flag set. I've tried to switch to all_squash but then I get "access denied" when trying to mount.
My /etc/idmapd.config file has my DOMAIN set properly as well as the entries for nobody-user/group.
The anonuid and anongid is set on the NFS server. Those UID's match the same account and group on the NFS client.

Any help is appreciated.
I've changed paths for obfuscation so please ignore path typos, I am sure those are all set properly.
