Yes, but it's scope was not immediately clear to me. Also, I couldn't
find the mapping feature you were mentioning; but my idmapd man page
comes from the nfs-common sources, while your idmapd.conf example (as
you explained) comes from libnfsidmap.

OK, now I understand :) As far as I can see, that would mean that anyone
with root rights on the client (thus being able to read the machine
keys) would have root rights on the server share, wouldn't it?

Best regards,
