NIS - "Could not read ypservers map" during "make"

[Mark Komarinski]

This is what I get for playing too much GTA: Vice City instead of
reading e-mail.

Instead of saying "what he said" to Ken's responses, here's my
thoughts.

That should probably be corrected, or have the implication changed.

I have that book.  It's actually a pretty poor book (ORA can be
hit or miss at times, sad but true).

Actually, NIS clients don't really require +:::::: anymore, or at
least not in all cases.  More appropriate would be /etc/nsswitch.conf.
NIS provides a lot more than just passwd entries, and nsswitch.conf
manages where the system looks for that information.

Then start ypbind.  Even if you're not using it for authentication, you'll
want it running.
