Yep, that's the conclusion we came to on the channel last
week. With the same domain entry in /etc/idmapd.conf on
server + client, his NFSv4 setup appears to be working
correctly.

When we started implementing NFSv4 in Solaris the NFSMAPID_DOMAIN
setting was something that just about everybody forgot to check
if they had the same sort of problem that Nikolai had. That made
it pretty high up my list of things to check before resorting
to suggesting snooping the wire :-)
