The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
As it turns out, it is WAD. But ultimately, I was overestimating what it was doing.
The NFS client sends UID and GID of the user to the NFS server. What I *thought* it would do, is look up what IBMi user profile on the NFS Server system had the corresponding UID and use that user profile to allow/deny access to the files. All it actually does is looks at the UID and GID on the files/directories to determine access. If there is no matching IBMi user profile with a matching UID or GID, then the 'anonymous user' user profile is used to allow/deny access to the files.
Apparently this fact is little known within IBM as it took a L2 guy to webex into our system for a while to determine what was going on.

On the mount definitely 'soft'
I've tried both version 3 and 4 and the behavior seems to be same either way. I have a PMR open to get IBM's help

In our testing I have USER1 on the client machine with UID(106) and
USER2 on the server machine with UID(106). When USER1 accesses the nfs
mount and gets an auth failure, according to the audjrne it is not USER2 getting the failure (because USER2 does have authority to the directory) but is showing the userid that we have specified in the export as the
anonyumous user. I see no other settings or knobs that need adjusted
in order to get it to use the UID found on the NFS server machine.
