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!).
