Suggestions:

-------------------------------

Use snoop to look at NIS+ traffic and login to a machine. I think that you
may have a NIS+ replica giving bogus information to your NIS+ clients.

-------------------------------

  Check to make sure your system clocks are in sync. NIS+'s
authentication info is time-sensitive.

-------------------------------

Solution:

This problem was evidently caused by several events that happened to
trigger an incompatiblity of some sort between UUCP and NIS+. We
discovered that NIS+ would "disappear" when the xx:11 and xx:41 uucp
cronjobs ran. To solve, we removed the SUNWbnuu and SUNWbnur packages
from all machines where it was not needed. The problem disappeared as
quickly as it had appeared.

Thanks for the help.
