从 1000 增加限制？

当我像这样进行搜索时

my $mesg = $ldap->search(
  base   => "OU=test,DC=example,DC=com",
  scope  => 'one',
  filter => '(objectClass=organizationalPerson)',
  attrs  => ['distinguishedName', 'displayName', 'sAMAccountName', 'employeeID'],
);

我只收到 1000 个条目，而我预计约为 20000 个。

是否可以在我的 Perl 脚本中增加此限制，或者是否必须在服务器上进行更改？

解决方案是像这样使用分页搜索

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

my $page = Net::LDAP::Control::Paged->new(size => 999);
my $cookie;

while (1) {
    $mesg = $ldap->search(
    base    => "OU=test,DC=example,DC=com",
    scope   => 'one',
    filter  => '(objectClass=organizationalPerson)',
    attrs   => ['distinguishedName', 'displayName', 'sAMAccountName', 'employeeID'],
    control => [$page]
    );

    $mesg->code && die "Error on search: $@ : " . $mesg->error;
    while (my $adentry = $mesg->pop_entry()) {

    # process $adentry
    }

    my ($resp) = $mesg->control(LDAP_CONTROL_PAGED) or last;
    $cookie    = $resp->cookie or last;
    # Paging Control
    $page->cookie($cookie);
}

if ($cookie) {
    print "abnormal exit\n";
    # Abnormal exit, so let the server know we do not want any more
    $page->cookie($cookie);
    $page->size(0);
    $ldap->search(control => [$page]);
}
