RE: Help diagnosing NIS breakage ?

Given the lack of response on this, I fortunately was able to 'downgrade'
back to sources dated 08 june 2003. Low and behold, NIS users again work.
There is undoubtedly something awry in the the latest sources, as I can
systematically recreate a 'broken' system. I will gladly provide shell access
to developers who wish to look into this. It would be nice to be able to stay
current on -CURRENT (heh).

Thanks.
