php - Laravel : Authentication fails every time -

i have created app laravel framework. use built-in laravel auth system. have quite strange problem it. returns false when try log user in with:

if (auth::attempt(['email' => $email, 'password' => $password])) {     log::info('user logged in');  } 

i sure email , password given correctly registered in mysql table named md.

in app/config/auth.php, have correctly set right table use store users.

'table' => 'md' 

i have correctly created required columns table (updated_at, created_at, remember_token).
