Well, man nscd.conf says differently; there's specifically tunable
paramters for positive caching and negative caching.  Not that this
would be the first time Solaris docs lied, but I'm pretty sure that I've
seen other stuff that talks about it and have seen some problems that
are best explained as nscd doing negative caching.

Hmm.  That completely contradicts what's published about it -- that it
was meant as an aide for NIS+.  At the time it was introduced, Sun was
still trying to give NIS the old heave-ho and never took interaction
with NIS into account except in the most superficial manner.

Which, again, sqaures with my own experiences with the beast. :)
However, here I'm relying on published material (Sun Press's _Solaris
Security_ for one) and don't have direct information from Sun.
