adldap2 laravel it is only returning 'false' - php

Question

I'm trying to use the adldap2 to access an adldap server.
it's everything ok with the server, i have used the Apache Directory Studio to test it.
I have followed all these instructions but withou success. All of my requests are returning 'false' or a empty collection.
what am i doing wrong?
Here are my files:
# \config\ldap.php
return [
'logging' => env('LDAP_LOGGING', false),
'connections' => [
'default' => [
'auto_connect' => env('LDAP_AUTO_CONNECT', true),
'connection' => Adldap\Connections\Ldap::class,
'settings' => [
'schema' => Adldap\Schemas\ActiveDirectory::class,
'account_prefix' => env('LDAP_ACCOUNT_PREFIX', ''),
'account_suffix' => env('LDAP_ACCOUNT_SUFFIX', ''),
'hosts' => explode(' ', env('LDAP_HOSTS', 'ldap.forumsys.com')),
'port' => env('LDAP_PORT', 389),
'timeout' => env('LDAP_TIMEOUT', 5),
'base_dn' => env('LDAP_BASE_DN', 'dc=example,dc=com'),
'username' => env(' cn=read-only-admin,dc=example,dc=com'),
'password' => env('password'),
'follow_referrals' => false,
'use_ssl' => env('LDAP_USE_SSL', false),
'use_tls' => env('LDAP_USE_TLS', false),
],
],
],
];
To test I using the web.php directly:
<?php
use Adldap\Laravel\Facades\Adldap;
Route::get('/api', function(){
$user = Adldap::search()->users()->find('newton');
dd($user);
return 'test page';
});
Here is my response error
false response result

Normaly a "false" is returned if there is an error in your Query or LDAP Settings. You could try to get the error with the ldap_error function.
In adldab2 there should be an method in your Connection from your Provider
$ad = new \Adldap\Adldap();
$config = [...]; // your config
$ad->addProvider($config);
$provider = $ad->connect();
// do your query stuff
$provider->getConnection()->getLastError()
