laravel Auth::login login not working

here is my code i am trying to login but its not working, data comes till before but something wrong in -> Auth::login($user1); though if i put Auth::login($user1); in if() condition it goes inside but not redirect in if condition,

        if(count($staff) > 0)
       {
       $staff['0']['type']='staff';
        $staff['0']['name']=$staff['0']['emp_name'];

        unset($staff['0']['emp_name']);
        Session::put('user',$staff['0']);

        $id= $staff[0]['id'];

        $user1 = Staff::find($id);
        //print_r($user);exit;
        //return Auth::login($user);
        Auth::login($user1);

        return redirect()->intended('/student');

    }
