[Bug 662711] Re: NFS user/group mapping not working in 10.10

[exa]

BTW, this is likely a 64-bit problem, as that number is -2, right? Maybe
it's an exceptionally bad programming error. I guess I won't see this
problem on i386.

So, maybe there is a serious 64-bit bug, in this case, why is the nfs-
user-server package removed from the distribution, why are the choices
being limited despite the fact that this bug has not been solved for
over a year? Or are you not testing these things on 64-bit machines?

BTW, the claims that this can be fixed simply by changing the
configuration seems to be wrong. The default config in 11.04 already
turns on that non-working idmapd.

This bug can be observed on a single machine running ubuntu 11.04 on
amd64 currently. I'll write more info as I have it.

Title:
  NFS user/group mapping not working in 10.10

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

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"
