RE: OpenLDAP watchdog

I haven't done it myself, but if I were to (And I probably will end up doing
something like that), I'd use PerLDAP to try a connection and maybe send an
e-mail or something, or attempt a restart, or something to that effect.
This has the advantage of giving you far much detailed control over what you
want to test, and how to react to problems ...
