No, processes should never run as nobody; nobody is reserved for
NFS as the default file ownership for anonymous and non-authenticated
access.
The noaccess user is destined for users "he who runs without access"

I have to ask whether this intention is documented anywhere. It seems

with entries like
finger stream tcp6 nowait nobody /usr/sbin/in.fingerd in.fingerd
fs stream tcp6 wait nobody /usr/openwin/lib/fs.auto fs
in them? And there's (p)identd which runs as "nobody" by default - didn't
that get the once-over from one Casper Dik for Solaris compatibility?
Do any Unix systems except Solaris have a "noaccess" passwd entry? Is it
a SVR4ism?

Hm; mine doesn't run as nobody but as sys (I only did the kernel
backend :-)
So I guess this is all a bit fuzzy; nobody for NFS existed and
it was (re|ab)used.
