| Yep, you channeled me alright.
Just dont do this. Eric wrote a nice writeup on this previously as well
that should be in the archives.
I reduce this to... If you or a vendor does this, what other bad habits do
you (or the vendor) have? It is just showing that someone is writing code to
work against AD and they don't know how to do it properly so probably
shouldn't. This will end up causing issues at some point. You may figure it
out right away when it does, you may not.
As to how to do it in PHP... I would recommend looking at the c++ docs on
MSDN using the LDAP API, if I recall the PHP LDAP libs are a very light
almost non-existent shell over the LDAP API. You will need to submit the
server control for paging and go from there.

I will channel the spirit of joe Richards until he reads this thread
and responds to it himself:
Raising the page size? No. No no. No no no. No no no no. No no no
no no. Did I mention...no?
Even if raising the page size from 1000 to 1500 doesn't create perf
issues for you initially, it sets a bad precedent. You set your max
pagesize to 1500 to fix this script issue. Then next month there's
another script/app for which 1500 is too small, so the developer asks
you to raise it to 2500, or 3000 or 5000.
At some point, and probably sooner than later, you're going to start
clobbering your DCs. Much better to have your apps/scripts use paging,
as it's much more predictable and well-behaved.
NB: I will admit to knowing absolutely -nothing- about PHP and so I
can't unfortunately instruct you on how to enable paging in your
script. I have to believe there's a way to do it, though.
