To answer my own question, I have found the following in Solaris FAQ:
Solaris 2 FAQ (p50 of 82)
4.7) Ypcat doesn't work on the netgroup table on a NIS+ server, why?
Yes, that is a known problem. The only operations allowed from a NIS client side on the netgroup table are the
ypmatches, but not ypcat (i.e. no support for yp_first(), yp_next() or yp_all() calls). The netgroup table is kind
of unique in this. The reason for this is that the netgroup table format changed quite significantly in NIS+ and
the NIS+ server would take a big performance hit in converting the netgroups table to YP (key-value) format.
I should have checked there before posting.
Argh. One would think Sun should give users an option to decide whether they want this
"performance hit" or not. A flag to rpc.nisd for example.
