Description MrKus 2023-03-13 15:11:11 MSK 
Пробую на:
ROSA Chrome Desktop 12.2 release 2021.1 for x86_64
ROSA Fresh Desktop 12.3 release 2021.1 for x86_64

Данным способом вводим в домен:
 
dnf install -y realmd sssd oddjob oddjob-mkhomedir adcli samba-common krb5-workstation

realm join -U admin dc.home.dom

systemctl enable sssd.service
systemctl restart sssd.service

kinit admin -> получаю билет
klist - Смотрю билет 

Далее пытаюсь смонтировать 

mount -t cifs //dc.home /mnt/soft -o user=admin,sec=krb5
получаю ошибку 

mount error(2): No such file or directory
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

если я введу команду
Без ключа sec=krb5, шара монтируется с вводом пароля без проблем. 

Пробовал менять конфиги и тд, все прописано куда нужно.
