Re: Very large results to return

[<Bob...@kp...>]

The size limit is imposed on the Server side, sigh.

There are two options (at least) --

     a) Talk to your Directory Manager about increasing the search-returns
limit (at least for your management account)
     b) Break-up your search into smaller chunks --

        $ouline   = ("ou=powerlinkcustomers");
        $oline    = ("o=adelphia.net");


        for i ("a" .. "z") {

           $filter = "mailhost=ms001" . $i . "dc3.adelphia.net";

          $message = $ldap->search(
             base      => ("$ouline, $oline"),
             scope     => 'sub',
             filter    => ("$filter"),
          );
     }


(Coded, but not verified.)

Hi everyone,

I am rather new to the ldap world, however, I have been tasked with
putting together a scipt that will get the current count of mailboxes on
our systems. We have 6 productions mail machines servicing approx 500,000
users. We are using the Netscape(Iplanet) package. I am running into a
size limit exceeded error when trying to get my results. Here is a snippit
of the code I am using.

$ouline   = ("ou=powerlinkcustomers");
$filter   = ("mailhost=ms001a.dc3.adelphia.net");
$oline    = ("o=adelphia.net");

$message = $ldap->search(
   base      => ("$ouline, $oline"),
   scope     => 'sub',
   filter    => ("$filter"),
   sizelimit => 0,
   timelimit => 0
);

This machine has about 72,000 mailboxes on it, so I wanted to use this as
a test. However after about 10 secs of work, then gives the following
error:

Error :: Sizelimit exceeded
Error Results: Net::LDAP::Search=HASH(0x32745c)

I tried filtering the search further by "attr" but still no luck.
Currently I have a script setup to use the ldapsearch tool, but that takes
approx 30 mins to work per machine. Any help would be great.
