Database Authentication Overview

Synchronized Database LDAP Authentication means that an LDAP user which successfully passes LDAP authentication will be created & synchronized to your local applications database. This is helpful as you can attach typical relational database information to them, such as blog posts, attachments, etc.

When a user is successfully authenticated, the Laravel Auth::user() method will return an instance of your configured Eloquent database model:

use Illuminate\Support\Facades\Auth;

$credentials = [
    'mail' => '[email protected]',
    'password' => 'secret',
];

if (Auth::attempt($credentials)) {
    $user = Auth::user();

    // Returns true:
    $user instanceof \App\Models\User;
}

Subsequent requests to your application with logged in users will retrieve the logged in user from your database, rather than your LDAP directory. This means your application will stay operational if connectivity to your LDAP server is dropped.
