Yes, there is some stuff in the NetBSD yp Makefiles that lets you
generate a solaris-compatible shadow map.

>What's ypwhich -m say?

It lists all the maps in zippy.local:/var/yp (except shadow.byname)
and shows the server as zippy.local.

I don't want the Solaris machine to be a slave server.  I want it to
be a client.  And my NetBSD slave server isn't seeing the
shadow.byname map either, so I don't think making the Solaris machine
a slave would make any difference.

I'm sure it's binding to the master; the bootup looks fine, and I can
"ypcat" any map from the server.

Yes, it contains:

The problem really seems to be that the NetBSD YP master doesn't know
that I want it to serve this shadow.byname file to clients.  I've read
all the YP man pages I can find, and I can't find any clue as to where
this gets configured.  Is there a hardcoded list of maps somewhere in
the ypserv code that I need to modify?  Or just a configuration file
I've missed in my searching?
