LDAPS implement

Hi,

LDAP connection (not anonymous) work. But when I change protocol ldap by ldaps and port 389 to 636, I have a blank page when I validate my login.
In log/php-fpm/www-error.log, I have this error :
[05-Oct-2023 19:26:48 Europe/Paris] PHP Fatal error: Uncaught TypeError: ldap_search(): Argument #1 ($ldap) must be of type LDAP|array, bool given in /usr/share/ocsinventory-reports/ocsreports/backend/AUTH/methode/ldap.php:83

thrown in /usr/share/ocsinventory-reports/ocsreports/backend/AUTH/methode/ldap.php on line 83

ldap.conf is not located at /etc/ldap/ldap.conf but in /etc/openldap/ldap.conf. I have all prerequis.

I have GLPI on this same server and it's work perfect in LDAPS with SSO.
Can you help me ?
