It seems there is no ready solution. Here is the closest thing i got to a working code yet its still not working... validation is not passed and users are not saved or created.
public function users_auth() {
$crud = new grocery_CRUD();
$crud->set_theme('datatables');
$crud->set_table('users_auth');
$crud->set_relation_n_n('groups', 'users_groups', 'groups','user_id','group_id','description');
$crud
->columns('first_name', 'last_name', 'email', 'phone', 'company', 'groups', 'active')
->fields('first_name', 'last_name', 'email', 'phone', 'company', 'groups', 'active', 'change_password', 'edit_password', 'edit_password_confirm')
->add_fields('username', 'first_name', 'last_name', 'groups', 'password', 'password_confirm')
->edit_fields('username', 'first_name', 'last_name', 'groups', 'active', 'change_password', 'edit_password', 'edit_password_confirm')
->change_field_type('change_password', 'true_false')
->change_field_type('edit_password', 'password')
->change_field_type('edit_password_confirm', 'password')
->change_field_type('password', 'password')
->change_field_type('password_confirm', 'password')
->set_rules('change_password', 'Change password', 'callback__change_password_check')
->set_rules('edit_password', 'Password', 'min_length[4]|max_length[20]')
->callback_edit_field('change_password',array($this,'_cb_change_password_field'))
->callback_edit_field('edit_password', array($this, '_cb_empty_password_input_field'))
->callback_edit_field('edit_password_confirm', array($this,'_cb_empty_password_confirm_input_field'))
->callback_before_update(array($this, '_cb_user_password_update'))
->callback_before_insert(array($this, '_cb_user_password_insert'))
->callback_after_update(array($this, '_cb_user_redirect'));
$output = $crud->render();
$this->_admin_output($output);
