Right. This is because the NFS when running "secure" expects "vouchsafe"
identification (ie: a connection from a reserved port to indicate the NFS
client is being run by root instead of being a user process that pretends
to be an NFS client). The "vouchsafe" is done by ensuring the remote client
is run as root by requiring a reserved port (which only root can allocate).
There is also an "overlap" problem where you can't export both "/" and
"/usr" if they aren't seperate file systems.
In theory, these are both fixed with the patchkit (works for me, anyway).
There's also some AIX 3.2 client stuff that's a pretty bizarre
interpretation of the RFC's, but this only applies to allowing remote
mounts by AIX 3.2 boxes of partitions exported from 386BSD.
