/var/mail and secure NFS

Trying to export /var/mail on my mail server and mount it on a client
box (both Solaris 8 in a NIS+ domain) with sec=dh option gave me decent
access for root on the client box but no access for normal users. All
kinds of attempts to access the directory return an error code of 22
EINVAL. It is not visible if I try to list /var as well.

Permissions for both the mount point and the exported dir are 1777
root:mail. The export has an rw option for the client machine and all
the other necessary stuff.

So the export looked like this:
share -F nfs -o sec=dh,rw=suns /var/mail

And the mount in /etc/vfstab on the client:
<server>:/var/mail - /var/mail nfs - no
sec=dh,rw,noac,hard,actimeo=0

After trying everything I removed the sec=dh option from both the export
and the mount and the above problem did not occur. What am I missing here?

Any help will be appreciated.
