Hi,

Be default the user_login validators like 'user_login_name_validate' etc are executed before your submit handlers and hence these things will still substitute the 'email' to the 'name' field, so your validation keeps on failing. In order to aviod that you need to flip the username for the entered email in your custom validator. Add the bewlo code in your form_alter


array_unshift($form['#validate'],'abhinav_login_validate');

function abhinav_login_validate($form, &$form_state) {
  if (isset($form_state['values']['name']) && $form_state['values']['name']) {
    if ($name = db_result(db_query("SELECT name FROM {users} WHERE LOWER(mail) = LOWER('%s')", $form_state['values']['name']))) {
      form_set_value($form['name'], $name, $form_state);
    }
  }
}

Now the 'name' element will contains the actual username for the corresponding email address. So automatically all the validations will get succeded. No need to add anything in the submit handler (so remove the function abhinav_login_submit()) since the default user_login will redirect the user to the correspoding user's page. Hope you understand the logic.
