What would it return if it is nisplus client or if not a client for
nis or nisplus?
Or if LDAP is being used?

This seems to return the nis server name.

I don't seem to have nisswitch on my machines
These are the binaries starting with nis which are present

nisaddcred   nischown     nisgrep      nismatch     nisprefadm   nistest
niscat       nischttl     nisgrpadm    nismkdir     nisrm
nischgrp     nisdefaults  nisln        nispasswd    nisrmdir
nischmod     niserror     nisls        nispath      nistbladm
