Sun vs. other NIS

[fetrow at milton.u.washington.edu]

I am having the %^&^%ist time with "Network Info Services" when I attempt to
use a Sun Master-Server (Sun 4/20 SunOS 4.1.1) with my IBM RTs (6150's w/ AOS)
and an IBM R/6000 (AIX).

If I use an RT as the YP server: All the machines are happy, including the
Suns.

If I use a Sun as the YP server: The Suns are happy but the IBM equipment
can't get any of the information.

Is anyone else having these problems? Even a message of "We tried it, it works,
you are doing something wrong" would be helpful.
