Switching user in laravel 5.4 - laravel

Question

I am switching users in laravel and I succeeded in that as well but the thing is when I redirect the user to the dashboard after successful login it redirects to login form instead I don't know what am I doing wrong. Here is the code I am using.
public function user_reauthenticate(Request $request) {
$input = Input::all();
$data = User::where('email', $input['email'])->first();
if ($data) {
if (Hash::check($input['password'], $data->password)) {
Session::put('email', $input['email']);
$newuser = Student::find($input['new_user']);
session(['orig_user' => $data->id]);
Auth::login($newuser);
return Redirect::back();
} else {
$response = 'Wrong Credentials';
}
} else {
$response = 'User does not exist';
}
}
Can anyone help me find out the issue?

You can log in with
Auth::loginUsingId(1);
New edited
// If you have the guard student and multiple auth
$auth = auth()->guard('student');
$objAuth = $auth->loginUsingId($input['new_user']);
//Single Auth
$objAuth = Auth::loginUsingId($input['new_user']);

Add this to your top of the file:- use Illuminate\Foundation\Auth\AuthenticatesUsers;
Afterwards add a if function like below in your already completed code:-
public function user_reauthenticate(Request $request)
{
use AuthenticatesUsers;
$input = Input::all();
$data = User::where('email', $input['email'])->first();
if ($data) {
if (Hash::check($input['password'], $data->password))
{
Session::put('email', $input['email']);
$newuser = Student::find($input['new_user']);
session(['orig_user' => $data->id]);
Auth::login($newuser);
if ($this->attemptLogin($request))
{
return $this->sendLoginResponse($request);
}
}
else
{
$response = 'Wrong Credentials';
}
}
else
{
$response = 'User does not exist';
}
}
After this method override this method as follows:-
protected function authenticated(Request $request, $user)
{
return redirect()->route('dashboard');
}
Check whether your dashboard route is named dashboard or if not name it.
