secure NFS problem

I've been trying to use sec=dh in an experiment to evaluate the secure NFS 
feature of Solaris 9. 

I followed the instructions in the docs on docs.sun.com (created a key for 
myself and my server and ran keylogin -r as root, added sec=dh to the 
/etc/dfs/dfstab file, and ran shareall). 

When I try to mount my home directory on a client it gets an error. 

 rpcsec: [ID 270986 kern.notice] NOTICE: authdes_create: unable to get client's netname: RPC: Failed (unspecified error) (error 16)

on the client. 

I don't know what it is referring to. 

Also, I tried with and without sec=dh in the automount map on the client.
Both ways failed. 

If I try to do a manual mount on the client I get

 error 7 (RPC: Authentication error)

and then when I do a df or try to ls the mount point it returns "invalid 
argument".

Can anyone give me pointers to good docs on this. We would like to 
implement this for our lab servers this summer.

Thanks,
Steve.
