chown return success, but ls & stat display the gid/uid nobody

Would it be possible to get a network trace to see what the
server is sending over the wire?

Also what exactly is this testing doing?

I will try to get network trace later, and reply,,,

In the Failed section, do the following test:
1. As root, touch a file in /nfs-mount, and check the file's uid/gid
   ls -l;  stat;
   Expected results: root.root
2. chown the file to qa:qa, check if chown success
   check exit code;
   Expected results: 0
3. and check the uid/gid   <<<-- FAIL in this step, in RHEL6.1 RHEL6.2 PASS
   ls -l; stat
   Expected results: qa.qa
   Actual results: nobody.nobody

This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.

Now I understand this is a feather implementation from bz705099,
but turn on/off by modules parameter is not a good UX.

Because this a feather of idmapd service,
Suggest add an option for rpc.idmapd, and user can choose turn on or off by
RPCIDMAPDARGS= in /etc/sysconfig/nfs.

I will close this, and open an other RFE type bugzilla:
