SSSD не удается перечислить вторичные группы Active Directory, "Нет записей tokenGroups для [пользователя]"

Я пытался настроить интеграцию Active Directory на моем хосте ubuntu 16.04 с помощью Realmd/SSSD (SSSD версии 1.13.4). Я могу войти в систему как пользователь AD, и перечисление групп работает с командой 'getent group ,' однако, установка не перечисляет должным образом членство пользователей в группах с командой 'id user@my.domain'.

Я приложу свои файлы конфигурации и соответствующие файлы журнала для SSSD (уровень отладки установлен на 9). Насколько я могу судить, анализируя файлы журнала, похоже, что SSSD не удается запросить tokenGroups для пользователя, утверждая, что запрос не возвращает ни одной группы токенов.

Я проверил, что tokenGroups можно получить с сервера Windows Active Directory, написав базовый .Net код, который запрашивает атрибут tokenGroups, и он правильно возвращает все группы. Однако SSSD, похоже, сталкивается с проблемой по той или иной причине. Я полагаю, что моя Active Directory использует схему rfc2307bis, и я пробовал с включенным и выключенным этим параметром, оба раза с ldap_group_member = member/uniqueMember, но это ничего не изменило (более того, я не думаю, что это влияет на поиск групп, если SSSD пытается использовать tokenGroups).

Я буду рад предоставить и другие журналы. Я также пытался сделать дамп wireshark, но пакеты LDAP зашифрованы с помощью SASL, и мне не удалось передать ключевую таблицу KRB5 в wireshark для расшифровки (возможно, файл ключевой таблицы зашифрован? Или, возможно, wireshark нужен файл keytab сервера? Мне было трудно расшифровать документацию wireshark по этому вопросу).
