I'm trying to implement an Ldap authentication in my laravel application, and I'm using laravel 9 and LdapRecord-laravel package

When I run the php artisan ldap:test command, I get an unsuccessful connection with the following message dap_bind(): Unable to bind to server: Can't contact LDAP server. Error Code: [-1] Diagnostic Message: null

This is the .env configuration

LDAP_LOGGING=true
LDAP_CONNECTION=default
LDAP_HOST=127.0.0.1
LDAP_USERNAME="cn=user,dc=local,dc=com"
LDAP_PASSWORD=secret
LDAP_PORT=389
LDAP_BASE_DN="dc=local,dc=com"
LDAP_TIMEOUT=5
LDAP_SSL=false
LDAP_TLS=false

Here is the config/ldap.php...

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | Default LDAP Connection Name
    |--------------------------------------------------------------------------
