Meanwhile, we went into production with the new NFS server and updated /etc/exports file
last weekend. The app that depends on the NFS server seems to be working just fine. But
in my case, the whole thing is wide open and the app doesn't seem to care a whole lot
about mapping user identities. Since it ain't broke, I don't think I'll try
to fix it.
I believe this is some arcane invocation of idmapd functionality.
Going back to
SunOS memories, it took the user name (or perhaps number) as trusted and
allowed you to access things if your usernum was the same on the client.
Understand that Solaris replaced SunOS about 20 years ago, and don't put full faith
in my memory.
In any case, if you have the same UID on all machines you will probably be fine,
but otherwise you will have to build a config file and run idmapd. The documentation
sucks, it isn't you, but "man idmapd" will get you started.
