[Bug] Use of undefined constant LDAP_ESCAPE_FILTER

[Nuvm]

Environment:

• LDAP Server Type: ActiveDirectory
• LdapRecord-Laravel Major Version: v2
• PHP Version: ^7.3
• Laravel version: 6.20.30

Describe the bug: Whenever I try to log in through my normal auth routes, I get this warning logged as an error in my logs: dev.ERROR: Use of undefined constant LDAP_ESCAPE_FILTER - assumed 'LDAP_ESCAPE_FILTER' (this will throw an Error in a future version of PHP) - in vendor\directorytree\ldaprecord\src\Models\Attributes\EscapedValue.php:107 It's as if ldap\ldap.php wasn't loaded properly.. Sorry in advance if this is obvious; I'm not really good with the laravel Auth flow.

Stacktrace:

I followed the database authentication and use the Active Directory built-in models. ldap:test succeeds.

LoginController

namespace CRMIDF\Http\Controllers\Auth;

use CRMIDF\Http\Controllers\Controller;
use CRMIDF\Providers\RouteServiceProvider;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use LdapRecord\Laravel\Auth\ListensForLdapBindFailure;

class LoginController extends Controller
{

    use AuthenticatesUsers, ListensForLdapBindFailure;

    protected $redirectTo = RouteServiceProvider::HOME;

    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }
}

config/Auth.php:

<?php

return [

    'defaults' => [
        'guard' => 'web',
        'passwords' => 'users',
    ],

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],

        'api' => [
            'driver' => 'token',
            'provider' => 'users',
            'hash' => false,
        ],
    ],

    'providers' => [

                    'email' => 'mail',
                ],
            ],
        ],
    ],

    'passwords' => [
        'users' => [
            'provider' => 'users',

            'expire' => 60,
            'throttle' => 60,
        ],
    ],

    'password_timeout' => 10800,

];

User model:

<?php

namespace CRMIDF\Models;

use Illuminate\Database\Eloquent\SoftDeletes;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
use LdapRecord\Laravel\Auth\AuthenticatesWithLdap;
use LdapRecord\Laravel\Auth\HasLdapUser;
use LdapRecord\Laravel\Auth\LdapAuthenticatable;

class User extends Authenticatable implements LdapAuthenticatable
{
    use SoftDeletes, Notifiable, AuthenticatesWithLdap;

    protected $fillable = [
        'name', 'email', 'password',
    ];

    protected $hidden = [
        'password', 'remember_token',
    ];

    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    public function employees()
    {
        return $this->hasMany(Employee::class);
    }
}

I've tried the User model with and without the HasLdapUser trait to no avail. Please note that our AD's distinguished names are in fact email addresses (email@domain.com).

Hi @Nuvm,

This is due to your web server having a PHP installation that does not have the ldap extension enabled. This is the only cause for this exception.

Please see:

• https://github.com/DirectoryTree/LdapRecord-Laravel/issues/138
• https://github.com/DirectoryTree/LdapRecord-Laravel/issues/206

I forgot about the webserver's php, you're right! Sorry for the bother and thank you!

No problem, happy to help @Nuvm! Glad you're up and running 😄
