Solved!

I happened to notice this line in /var/log/messages on my NFS server when I was attempting to mount an export from the remote client:

Feb 28 15:54:02 storage1 rpc.idmapd[1651]: nss_getpwnam: name 'nobody' does not map into domain 'localdomain'

This caused me to look at the first few lines of /etc/idmapd.conf:

[General]
#Verbosity = 0
# The following should be set to the local NFSv4 domain name
# The default is the host's DNS domain name.
#Domain = local.domain.edu

I then added Domain=subdomain.mycompany.com under the commented out "Domain" line. Saved, exited and then ran/etc/init.d/rpcidmapd restart and /etc/init.d/nfs restart.

Ubuntu

vim /etc/idmapd.conf
add Domain=example.com

reboot
