Have you tested it on amd64?

I'll take a look at the config if it can indeed be solved by trivial
configuration. IIRC, on the machine I tested, I did check the proposed flags
and they were correct. I didn't even touch them.

Cheers,

Title:
  idmap should be started by default because mount.nfs now negotiates
  NFSv4 before NFSv3

Status in “nfs-utils” package in Ubuntu:
  Triaged

Bug description:
  I have a NFS client/server setup where both client and server are
  Ubuntu 10.10 (both upgraded from 10.4)

  To make UID and GID mapping trivial, I've made sure that clients and
  server all have the same users and groups with the same IDs. This used
  to work fine. However now the client is always displaying 4294967294
  for the UID and GID but - and here is the strange bit - if I create a
  file on the client it shows up on the server with the correct user and
  group (but on the client still with 4294967294).

  I posted this originally on the forums, and decided to file this bug
  when 2 other people reported having the same problem since upgrading
  to 10.10. In both cases they were using Ubuntu as client and Solaris
  as server. See thread here:
  http://ubuntuforums.org/showthread.php?p=9983624

  Additional info:

  /etc/exports line on the server:
  data/fileserver 192.168.1.0/255.255.255.0(rw,sync,no_subtree_check)

  /etc/fstab line on the client:
  htpc:/data/fileserver /data/fileserver nfs defaults 0 0

  Trying to chown a file on the client gives the error "chown: changing
  ownership of `somefile': Invalid argument"
