However, I got more response to my summary than to my original question.
It turns out that this root power was *not* available in Solaris 2 until
very recently, when it was added back in. A sentence was added to the
end of the paragraph from which I quoted above:
If NIS is in
effect, superuser on the root master can change any password
without being prompted for the old NIS passwd , and is not
forced to comply with password construction requirements.
It turns out that if this had been a later OS, or had certain patches
(below), it would have worked.
Casper Dik explained it best (as usual). Thanks also to Niall O Broin
and Gerard Henry.
