I'm not an expert on idmap, but a few quick notes that might help.
1. The log flag is IDMAPPER
2. You are running nfsv4, right? (just checking...)
3. The domains on the client and server have to match exactly, even to
the case.
4. NFSIDMAP is on by default, so it's likely to be on for the CentOS
SIG, but Kaleb would know for sure

Hello all,
I'm attempting to configure my NFS Ganesha installation with nfsidmap,
using local usernames. This is a home environment using trusted hosts
and no central authentication yet, so I'm finding a lot of documentation
on NFS Ganesha in enterprise environments, or in environments which
accommodate self-compiling it with different configure flags.
Right now, I have nfsidmap configured on my Ganesha server and on my NFS
client, with matching domains, and users with matching names, but
different UIDs on each. I have set the option nfs4_disable_idmapping=N
(which disables idmapping when sec=sys) for nfsd and nfs on the server
and client respectively. But files created from the client maintain the
client user's UID when inspected on CephFS, rather than being translated
to the server user's UID.
I can't seem to figure out what configure flags the version in the
CentOS SIG repo has, nor what the requirements are to allow Ganesha to
use nfsidmap, nor what logging to enable to debug the process. Is there
current documentation or a guide on interactions between the two, so
that I can narrow down my issue?
Thanks in advance, and warm wishes,
Sasha
