SizeLimit exceeded using Net::LDAP::Control::Paged

active directory returns only 1000 records

According to all the documentation I've read, the maximum size of a result set when querying Active Directory is 1000 records. If you need more than 1000, you are told to use Net::LDAP::Control::Paged in order to page through and get more than 1000 records, which I have attempted to do. For some reason, I am still only getting 1000 records back, despite using a paged control. I am using the same code that others have claimed to be using successfully without any luck. Am I missing something here? Please note that I do not have administrative access to the AD servers, so changing the configuration is not an option for me. I've pasted the relevant code below so you can point out whatever I might have done wrong.

#!perl -w

use strict;
use Net::LDAP;
use Net::LDAP::Control::Paged;
use Net::LDAP::Constant qw( LDAP_CONTROL_PAGED );

my $LDAPServer      = "<LDAP SERVER ADDRESS>";
my $base        = "<BASE DN>";
my $user                = "<LDAP USER>";
my $pass                = "<PASSWORD>";
my $page                = Net::LDAP::Control::Paged->new(size => 1000) or die $!;
my $errorConnectionStr  = "";
my $ldap;
my $mesg;
my $cookie;

$ldap = Net::LDAP->new($LDAPServer);
$mesg = $ldap->bind($user, password => $pass, version => 3);

print OUT "sAMAccountName,sn,givenName\n";

my $filter = "(&(objectClass=person)(!(userAccountControl:1.2.840.113556.1.4.803:=2))(!(objectClass=computer)))";
my @attribs = ("sn", "givenName", "sAMAccountName", "distinguishedName");

my @args = (
        base    => $base,
        scope   => 'sub',
        filter  => $filter,
        attrs   => @attribs,
        pagesize => 1000,
        control => [$page]

while(1) {
    $mesg = $ldap->search(@args) or die $!;

    while (my $entry = $mesg->pop_entry()) {
        my $print = 1;

        my $dn = $entry->dn();
        my $uid = $entry->get_value('sAMAccountName');
        my $ln = $entry->get_value('sn');
        my $fn = $entry->get_value('givenName');

        if($dn =~ m/.*Resources.*/) {
            $print = 0;

        if(defined($uid) && defined($ln) && defined($fn)) {
            if($print == 1) {
                print OUT "$uid,$ln,$fn\n";

    my ($resp) = $mesg->control(LDAP_CONTROL_PAGED) or last;
    $cookie = $resp->cookie or last;

if($cookie) {
    print "Abnormal exit\n";


You need attrs => \@attrs, in @args. Without the backslash you're interpolating an odd number of elements ('attrs' plus the four elements of the array) and the search method doesn't see the pagesize argument.

Using LDAP Controls with Net::LDAP, As you might expect with Net:: LDAP, controls are instantiated as objects. more than 1000 entries, the script aborts with the error message Sizelimit exceeded. The paged-results control informs the directory server that the search might  Net::LDAP::Control::Paged provides an interface for the creation and manipulation of objects that represent the pagedResultsControl as described by RFC 2696. The control is allowed on LDAP search requests ("search" in Net::LDAP) only. On other operations it will - depending on the value of the parameter critical - either be ignored or lead to

I just used it for the first time, and it works here. My seach is pretty simple (show all objects in a container). I'm listing 11.5k groups by grabbing them in 800-group pages. My code is nearly identical to yours (it's a mixture of the example on the Net::LDAP::Control::Paged man page and yours), except I don't specify a page size in the search:

while (1) {
   my $mesg = $x->{ldap}->search(base => $x->{config}->{gbase},
                                scope => 'sub',
                              control => [$page],
                               filter => 'cn=*',
                                attrs => \@attrs,
   die "LDAP error: server says ",$mesg->error,"\n" if $mesg->code;

   foreach my $entry ( $mesg->entries ) {
      my $cn   = $entry->get_value('cn');
      my $desc = $entry->get_value('description');
      print "$cn - $desc\n";

   # Get cookie from paged control
   my($resp)  = $mesg->control( LDAP_CONTROL_PAGED )  or last;
   $cookie    = $resp->cookie or last;

   # Set cookie in paged control

Getting around Active Directory search size limit via ldapsearch, Ldapsearch provides '-E' option that allows to perform paged searches. We can ask for all items of a large result set simply by providing the right  Paged results, as specified in the RFC 2696, does not allow to get over the server sizeLimit. The RFC clearly states "If the page size is greater than or equal to the sizeLimit value, the server should ignore the control as the request can be satisfied in a single page".

You can't use a size of 1000 since it's the AD limit and hence doesn't page. Needs to be something less than that. Try 999 and be happy.

  • I believe this is already answered here.
  • @sferencik No, the code that I'm using in my example is using LDAP::Control::Paged as the page you linked explains in its answer. The question you linked is asking how to return more than 1000 records, and the answer provided is to use the same control I'm trying to use that is not working.
  • then why my AD accepts more than 1000 ? Main issue is dropped backslash before @attribute variable. second problem is paging, but here it is ok. AD supports LDAP feature, fetching objects as pages with multiple continious searches.
