Well, I finally dove into libnfsidmap and nfs-utils and tracked it down
to a bug in nfs-utils.  Sorry, I should have said we were still on
nfs-utils-1.2.6, which seems to be pretty old by now.  This looks like
the commit that fixed it:

http://git.linux-nfs.org/?p=steved/nfs-utils.git;a=commit;h=fd27c638898010438d404cd17120729ef1d680e2

This change is in 1.2.7 and, after upgrading to it on my test box,
chgrp works once again.  Sorry for the noise, I should have tried
upgrading nfs-utils first (at least I know a lot about the new idmapper
now!).

Thanks for the help,
Brian
