Мы настроили рабочий пакет SSSD + Samba + Krb5, работающий для авторизации пользователей домена на машинах Linux. Авторизация работает нормально, но группа getent ПРИМЕР не возвращает полный список пользователей в группе. В то время как мне бы команда показывает ту конкретную группу, к которой принадлежит пользователь
id mshepelev пример команды (pam_nas_admins группа существует):
~$ id mshepelev
uid=1019815042(mshepelev) gid=1019817477(linuxadm) группы=128(vboxusers),132(libvirtd),
1019817706(exchange_terminal),1019800512(domain admins),1019800513(domain users),1019817356(it dept base),1019817232(printer_it),
1019817477(linuxadm),1019801141(buh),1019817834(pam_nas_admins)....
группа getent pam_nas_admins образец (в этой группе нет мшепелева):
~$ getent group pam_nas_admins
pam_nas_admins:*:1019817834:nhramchihin,apyataev,
vshuykov,isaidashev,admin,nrosnovskiy,itugunov,
malfereva,mdimitraki,izinoviev,gkulakov,mcherenkov,kfomchenko,mkotov,aromanovskiy
Обновить
Такая же ситуация возникает на другом ПК, но для пользователя isaidashev - наоборот. Мне бы команда возвращает полный список и группа getent pam_nas_admins возвращает всех, кроме самого пользователя (вывод Мшепелев пользователь, но не имеет Исайдашев пользователь)
