Hmm... Not sure this is a great idea, but the concept I was looking at was
changing default permissions for objects in the schema:;en-us;265399

Use that very very very carefully.  You could ruin the entire AD Forest
implementation irreparably in nothing flat.  It could also solve your
problem if used correctly.

If this is for a subset of objects instead, this might be a better way to

I suggest testing to make sure you have what you want coupled with careful
documentation of current settings.

I am looking for a way for an admin group (for example) to store mildly
sensitive information using AD, and blocking access to that information for
my LDAP users, for example, remote mail clients who use LDAP for address
lookup; as these people authenticate with a username and password, as far as
I can tell they could lookup any AD parameter unless it has restricted
rights. I admit most wouldn't know the attributes are there or how to query
them, but why take a chance?

If indeed it's a question of managing rights on AD attributes, i confess I
have not gotten far enough into AD to know where to do that. If you have
pointers for self-study I'd be delighted to have them. Yes, I do know the
dangers of messing with the schema; we have a development server.
