Synopsis: [nfs] chown and chgrp operations fail between FreeBSD 9.1RC3 NFSv4 server and RH63 NFSv4 client

State-Changed-From-To: open->closed
State-Changed-By: rmacklem
State-Changed-When: Sun Dec 2 00:20:25 UTC 2012
State-Changed-Why: 

This bug is caused by Linux 3.3 or greater kernels defaulting
to using numeric uids/gids in the owner and owner_group strings.
Support for this is defined in an internet draft that has not
yet been published as an RFC. To swich the Linux server to the
old behaviour you may:
- create /etc/modprobe.d
- put a file in there called nfs.conf with the following line in it
options nfs nfs4_disable_idmapping=N
Support for this new behaviour was added to head as r240720 and has
been MFC'd to stable/8 and stable/9.
