Cisco ASA: разрешение и запрет доступа к VPN на основе членства в группе AD

У меня Cisco ASA 5505 подключается к серверу Active Directory для проверки подлинности VPN. Обычно мы ограничиваем это определенным OU, но в этом случае пользователи, которым нужен доступ, распределены по нескольким OU. Итак, я хотел бы использовать группу, чтобы указать, какие пользователи имеют удаленный доступ. Я создал группу и добавил пользователей, но мне сложно понять, как запретить пользователям, не входящим в эту группу.

Прямо сейчас, если кто-то подключается, ему назначается правильная групповая политика «companynamera», если они находятся в этой группе, поэтому отображение LDAP работает. Однако пользователи, которые не входят в эту группу, по-прежнему проходят проверку подлинности, и их групповая политика становится путем LDAP их первой группы, то есть CN = Domain Users, CN = Users, DC = example, DC = com, а затем все еще разрешен доступ. . Как добавить фильтр, чтобы отображать все, что не "companynamera" к без доступа?

Конфигурация, которую я использую (с удалением некоторых вещей, таких как ACL и сопоставления, поскольку они здесь просто шум):
