| The 3rd bit controls the "list object" behaviour not
"list contents". The former is only available to use in an ACE if the 3rd bit is
set to 1. If it's set to 0 or "not set" then "list contents" is available but
not "list object".
This article explains further.

PS I
tested this quickly and it works as described
above.

ActiveDir@xxxxxxxxxxxxxxxxxxSubject: [ActiveDir] dsHeuristics and
list object access mode
dsHeuristics can be used to control whether the 'list
contents' ACE has an affect. So if the attribute is set to 001 then this means
that if you haven't got list contents permission on a container then you can't
see what's under it. Whereas if dsHeuristics is the equivalent of 000 then list
contents doesn't matter so much and you can see what's under a container without
explicit list contents rights just as an authenticated user.
At least this is what I've finally arrived at by reading different
contradictary sources. I'm still a bit sceptical by all of this, indeed I reckon
that somewhere along the various cut and paste jobs someone has got totally the
wrong idea. So this has all started me off doing some
experimenting.........
No matter what state the dsHeuristics attribute is set to ,
000 or 001. (all zeros.). Removal of the list contents right stops someone looking
at what lives under the object. Likewise granting it lets whoever has the
permission go through the contents.
So I'm looking for some clarification from practical experience as I no
longer believe the spin that says you need to set dsHeuristics to 001 (or full
001000..... equivalent) to be able to effectively use or remove the 'list
contents' permission.
Does list object access mode work irrespective of the third bit of the
dsHeuristics value for other people?
If it makes no difference, as I'm seeing, what does that value actually do
as it doesn't seem to tie up with what some people are claiming?

| The DSheuristics setting activates or de-activates the
List Object permission, not the List Content permission - however, you have to
use both in conjunction to reach most goals in respect to hiding data in AD.
I've created this table for other stuff I'm
working on to clarify the confusion a bit.
(btw, the first two bits
of this setting are also important, but not for permissioning - they control
name resolution during AD searches.)
