如何使用不同的数据库登录？我用不同的用户和数据库登录时遇到问题？

AuthController

public function loginAksi(Request $request)
{
    if ($request->email == null or $request->password == null) {
        return redirect()->back()->with(['error' => 'Masukkan Email atau Password !']);
    } else {
        if (Auth::attempt([ 'email' => $request->email, 'password' => $request->password ])) {
            $user = Auth::user();
            if($user->level == 1){
                return redirect()->route('admin.dashboard')->with(['success' => 'Selamat Datang']);
            } elseif($user->level == 0){
                return redirect()->route('user');
            } else {
                return redirect()->route('userlansia');
            }
        } else {
            return redirect()->back()->with(['error' => 'Login Gagal !']);
        }
    }
}

我已经成功地使用了用户登录从默认数据库，如用户，现在我想登录一个不同的数据库

兰莎模型酒店

protected $fillable = [
        'id_lansia',
        'nama_lansia',
        'tempat_lahir',
        'tgl_lahir',
        'alamat',
        'No_tlp',
        'NIK',
        'No_BPJS',
        'email',
        'password',
        'level',
        'user'  
    ];

    protected $table = 'lansias';

    protected $primaryKey = 'id_lansia';

auth.php

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

'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\User::class,
        ],

kernel.php

protected $routeMiddleware = [
      'admin' => \App\Http\Middleware\AdminMiddleware::class,
      'user' => \App\Http\Middleware\UserMiddleware::class,
      'userlansia' => \App\Http\Middleware\LansiaMiddleware::class,
];

有人能帮忙吗？
