RE: Help diagnosing NIS breakage ?

Ok...Been systematically stepping through the sources to locate the point at
which NIS became broken.  Here are the results:

-CURRENT src date       report
-------------------     -------
2003.06.18.00.00.00     success
2003.06.25.00.00.00     success
2003.06.26.00.00.00     success
2003.06.27.00.00.00     sucesss
2003.06.28.00.00.00     failure
2003.07.01.00.00.00     failure
2003.07.09.00.00.00     failure
latest (last night)     failure

So, something between 27 and 28 June resulted in this NIS breakage. Hopefully
this will jog someone's memory and give ideas as to my/our next step as to
diagnosing/repairing what's wrong here. I have a test box with src's and obj
's from both 27 and 28 june availabe for testing, should someone like to ssh
in and poke around.

Thanks in advance.

Robin.
