Thanks, Brian.  I had finally got someone to point me to ntdsutil - now
I'm trying to make it work.  The various on-line things from Microsoft
aren't that informative.  But at least I now know where to look.

Subject: RE: Active Directory and LDAP sizelimit

Hi,

Windows 2000 AD has a default limit of 1000. I THINK you can change this
with the ntdsutil.exe utility on a domain controller. This utility can
be used to examine and set LDAP parameters in AD. I THINK that these
settings are global for your entire forest. The Q article:
http://support.microsoft.com/?kbid=271088 goes into detail as to how to
use this utility. http://www.jsiinc.com/SUBJ/tip4600/rh4678.htm explains
the units of the various AD LDAP parameters. Also, Active Directory
supports paged searches....which is what I do to retrieve more than 1000
objects. Using paged controls I routinely retrieve 20-30K objects via a
single query from my AD forest which has the default setting of 1000 for
MaxPageSize.

Subject: Active Directory and LDAP sizelimit

From:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/h
tml/vbtsksearchingactivedirectoryhierarchy.asp

"The maximum number of entries to return by setting the SizeLimit
property. 
Note   If the maximum number of returned entries and TimeLimit
properties exceed limitations set on the server, the server settings
will override the component settings."

If I set sizelimit in the Perl script to something LESS than 1000, that
works.  I get the smaller number of returns.  If I set it to anything
more, or to 0 (which is supposed to give unlimited returns), I can only
get 1000.

I believe Perl and Net::LDAP are working properly.  I think the problem
is this mysterious "limitations set on the server" that is stopping me.
And I can't figure out how to change that.

Subject: RE: Scope=>'sub' not working??

Stranger and stranger.  I just did a comparison of the two searches.
The top-down one gets 265 out of 651 objects in the OU.  I am beginning
to suspect some limit on the number of returned objects allowed.  I seem
to recall once hitting a 1000-object limit on AD LDAP returns - which is
killing for ADs of our size.

Subject: Scope=>'sub' not working??

I'm trying to search the whole of our AD for computer objects (using the
Perl Net::LDAP module).  I just put in as searchbase:

my $searchbase='DC=com,DC=unet,DC=auckland,DC=ac,DC=nz';

Looking for computers so I put in:

my $filter="(&(objectclass=User)(objectcategory=computer))";

I do a search:

my
$results=$ad->search(base=>$searchbase,filter=>$filter,attrs=>$attrs);

(scope=>'sub' is supposed to be the default, but I have also tried with:

my
$results=$ad->search(base=>$searchbase,filter=>$filter,scope=>'sub',attr
s=>$attrs);

)

I don't get everything.  If I put in a full OU:

my $searchbase='OU=Staff Computers,OU=COM
Computers,DC=com,DC=unet,DC=auckland,DC=ac,DC=nz';

I get objects under that OU.  I haven't yet looked to see whether my
scope=>'sub' search gets some of those computers or not.  But I don't
want to look under a particular OU; I want to look in the whole AD - one
of the things I am looking for is computers that have got into the wrong
location.
