Login with LDAP not working

I'm trying to get the login with LDAP working, but I'm having no luck with it.

My current version:
PHP Version : 8.2.4
Web Server : Apache/2.4.56 (Debian)
Database Server : Debian 11 version 10.5.18-MariaDB-0+deb11u1
Version OCSReports: 2.11.1-nightly-2023-03-27

LDAP ist enabled in php.ini with "extension=ldap"
LDAP is enabled in var.php with "define('AUTH_TYPE', 2);"

My current settings:
CONEX_LDAP_SERVEUR= ldap://dc.company.local
CONEX_ROOT_DN= CN=ReadOnlyLDAP,OU=Passive Accounts,OU=company,DC=company,DC=local
CONEX_ROOT_PW= somepassword
CONEX_LDAP_PORT= 389
CONEX_DN_BASE_LDAP= OU=Company-Management,OU=sub-company,OU=sub-companys,OU=company,DC=company,DC=local
CONEX_LOGIN_FIELD= sAMAccountName
CONEX_LDAP_PROTOCOL_VERSION= 3
CONEX_LDAP_CHECK_DEFAULT_ROLE= Administrators
CONEX_LDAP_NB_FILTERS= 1
CONEX_LDAP_FILTER1=
CONEX_LDAP_FILTER1_ROLE= Administrators

On the webpage it's only showing a blank page after attempting to login with ldap credentials.
And I'm getting the following error message in /var/log/apache2/error.log
"[Wed Apr 19 13:08:45.182037 2023] [proxy_fcgi:error] [pid 9952] [client xxx.xxx.xxx.xxx:56080] AH01071: Got error 'PHP message: PHP Warning:  Undefined variable $filter in /var/www/html/backend/AUTH/methode/ldap.php on line 99; PHP message: PHP Deprecated:  trim(): Passing null to parameter #1 ($string) of type string is deprecated in /var/www/html/backend/AUTH/methode/ldap.php on line 99; PHP message: PHP Warning:  Undefined variable $filter in /var/www/html/backend/AUTH/methode/ldap.php on line 99; PHP message: PHP Warning:  ldap_bind(): Unable to bind to server: Invalid credentials in /var/www/html/backend/AUTH/methode/ldap.php on line 143; PHP message: PHP Fatal error:  Uncaught TypeError: ldap_search(): Argument #1 ($ldap) must be of type LDAP|array, bool given in /var/www/html/backend/AUTH/methode/ldap.php:102\nStack trace:\n#0 /var/www/html/backend/AUTH/methode/ldap.php(102): ldap_search()\n#1 /var/www/html/backend/AUTH/methode/ldap.php(66): search_on_loginnt()\n#2 /var/www/html/backend/AUTH/methode/ldap.php(45): verif_pw_ldap()\n#3 /var/www/html/backend/AUTH/auth.php(94): require_once('...')\n#4 /var/www/html/require/header.php(321): require_once('...')\n#5 /var/www/html/index.php(44): require('...')\n#6 {main}\n  thrown in /var/www/html/backend/AUTH/methode/ldap.php on line 102', referer: https://ocs.company.de/index.php"

For me it looks like in necessarily need a filter to get ldap working. Even though  i just want to give everyone from our managment the option to login as Administrator. And have a Super Admin as Backup, just with a local login.

'Unable to bind to server: Invalid credentials' seems clear, no ?

Everyone as Administrator ? Are you sure ?
