`ldap_search` not working on debian 11 with PHP8.2 and ldap module compiled from source

Description

The following code:

Hey, I use a self compiled php8.2-ldap extension in an php8.2 setup (Default PHP8.2 container from docker php 8.2.28-cli-bullseye) .
The following code always return the ldap error Operations error (ldap_error-code 1)

<?php
$ldap_host = "myhost"; 
$ldap_dn = "DC=host,DC=site";
$ldap_username = <user>; 
$ldap_password = <pw>; 
$options = [
        'host' => $ldap_host,
        'dn' => $ldap_dn,
        'username' => $ldap_username,
        'password' => $ldap_password,
];


$ldapconn = ldap_connect($options['host']);
ldap_set_option($ldapconn, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ldapconn, LDAP_OPT_REFERRALS, 0);

@ldap_bind($ldapconn, $options['user'], $options['password']);

$filter = "(objectClass=*)";

@$search = ldap_list($ldapconn, $dn, $filter);

if (!$search) {
        var_dump([
                '$search' => $search,
                'error' => 'LDAP search failed',
                'ldap_error' => ldap_error($ldapconn),
                'ldap_errno' => ldap_errno($ldapconn),
                'base_dn' => $dn,
                'filter' => $filter
        ]);
}
ldap_unbind($ldapconn);

?>

ldap_connect and ldap_bind are working fine. It is also possible to get the base dn using the following codeblock:

$read = ldap_read($ldapconn, '', 'objectClass=*', ['defaultNamingContext'], 0);
$data = ldap_get_entries($ldapconn, $read);
$dn = $data[0]['defaultnamingcontext'][0] ?? null;

That means ldap_read and ldap_get_entriesare working.

If I use the same code from above on ubuntu using pre-compiled php8.2-ldap.so module from ubuntu repository, the code runs fine without any errors. So I can be sure, that the the credentials from $options are correct. Also an ldapsearch from command line with the same credentials and filters returns valid results.

I compile the php8.2-ldap module during docker-build phase using that code:

RUN apt-get update && apt-get -y install pkg-config [...] ldap-utils libldap-common libldap2-dev\
[...]
&& docker-php-ext-configure ldap --with-libdir=/lib/x86_64-linux-gnu/ \
&& docker-php-ext-install ldap \
[...]

Resulted in this output:

`Operations error`  (ldap_error-code 1)

But I expected this output instead:

I expected a list of LDAP entries

Any idea, what's goinig on here? Did a miss a compiler-option or an package?

Operating System

Debian 11

Bắt đầu bằng cách tái hiện lỗi ldap_list trong bản build Docker Debian 11 PHP 8.2, sử dụng các đường dẫn ldap_connect, ldap_bind, ldap_read và ldap_get_entries được mô tả trong báo cáo. So sánh module đã biên dịch với module Ubuntu đang hoạt động và ldapsearch trên dòng lệnh, sau đó ghi lại một khác biệt đã được xác nhận về package hoặc compiler và xác minh rằng tìm kiếm LDAP trả về các entry.
