Cannot write to nfsv4 share

I am running 8.0-RELEASE.
I am able to mount an nfsv4 share on a Debian GNU/Linux server, but I cannot
write to it. I realise that nfsv4 is experimental on FreeBSD, but I am
tantalisingly close to getting it working and thought that someone here could
advise, or point me to some (web) reference. I have googled but have not found
anything relevant to this problem.
I have enabled the following in /etc/rc.conf:
I have passed the domain "localdomain" to nfsuserd via nfsuserd_flags because
that is what it is set to (by default) via /etc/idmapd.conf on the Linux
I mount the remote location using:
# mount -t nfs -o nfsv4,rw 192.168.x.x:/freeagent /mnt
which succeeds.... (either with or without the "rw" option)
/dev/ad2s1a on / (ufs, local)
devfs on /dev (devfs, local, multilabel)
/dev/ad2s1e on /tmp (ufs, local, soft-updates)
/dev/ad2s1f on /usr (ufs, local, soft-updates)
/dev/ad2s1d on /var (ufs, local, soft-updates)
192.168.x.x:/freeagent on /mnt (newnfs)
When I execute an ls -al on /mnt all the directories have the correct
permissions, except for one.... (NOTE THE GROUP -- 32767)
drwx------ 2 root 32767 16384 Jul 5 12:28 lost+found
If I try, either as root, or as my regular user account, to write to the drive
$ cd /mnt
$ touch junk
touch: junk: Permission denied
I have checked the directory permissions for my user and they are correct. I
use the same username (and group) on both the FreeBSD desktop and the Linux
(NFS4) server and, according to the permissions, I own and should be able to
write to the share:
$ cd /mnt
$ ls -ald .
drwxr-xr-x 7 username username 4096 Dec 11 13:37 .
I can successfully read from the nfs4 mounted drive, but I cannot write to it.
Has anyone got any idea where I have gone wrong. (If I boot to Linux on the
same client I can successfully mount and read/write, so I'm reasonably certain
the server side is set up correctly.)
