NFS: does not map into domain ‘localdomain’

I stumbled on a strange problem regarding NFS, which I hadn’t used for a while on my server. I had some old exports which worked last time I used them, but not any more. I was doing an rsync and suddenly saw messages about chgrp or chmod failing. These messages are expected when uid/gid is not matching between server and client, so what’s up?

Running dmesg showed me messages like these:

NFS: v4 server warhammer does not accept raw uid/gids. Reenabling the idmapper.

Looking in /var/log/syslog I saw messages like these:

rpc.idmapd nss_getpwnam: name ... does not map into domain 'localdomain'

I finally found a working solution here.
