NFSv4 "stronger authentication required" error

I've run into a strange problem while trying to mount from FreeBSD
9.0-RC3 to anything I can find using NFSv4.
The command I'm using is:
#mount -v gorkon:/dustbin /tmp/test
This returns the following immediate information on a Debian 6 Linux box:
mount: no type was given - I'll assume nfs because of the colon
mount.nfs: timeout set for Thu Jan 5 17:37:40 2012
mount.nfs: trying text-based options
mount.nfs: mount(2): Permission denied
mount.nfs: access denied by server while mounting gorkon:/dustbin
There's no log entry that I can find on the server (gorkon), and the
following log entry is in my syslog for the debian box:
[30082.224612] RPC: server gorkon requires stronger authentication.
The NFS server has nfsuserd running, rpcbind running. I've tried to set
the share in /etc/exports to use sec=sys (and connect the same way). I
don't have Kerberos set up on this network, and I'm not about to start.
The Debian NFSv4 servers do connect to a Solaris 10 NFSv4 server, and
the FreeBSD box can't mount its own shares over NFS if I force use of
nfsv4 (error is mount_nfs: /tmp/test, : Permission denied). A FreeBSD
8.2-RELEASE box won't mount either, same error.
The Solaris 10 box also cannot mount the FreeBSD box's mount. The error
for this machine is :
genunix: [ID 664466 kern.notice] NFS compound failed for server gorkon:
genunix: [ID 532867 kern.warning] WARNING: NFS server initial call to
gorkon failed: permission denied.
NFSv3 mounts work fine.
Anyone know what's going on?
