`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

Inizia riproducendo il problema di ldap_list nella build Docker Debian 11 PHP 8.2, utilizzando i percorsi ldap_connect, ldap_bind, ldap_read e ldap_get_entries descritti nel report. Confronta il modulo compilato con il modulo Ubuntu funzionante e con ldapsearch dalla riga di comando, quindi documenta una differenza confermata nel pacchetto o nel compilatore e verifica che la ricerca LDAP restituisca delle voci.
