Добрый день.
Переход на linux сервера в качестве рабочих мест. Тестирую на rosa fresh 12.3.
Сервера в домене - авторизация, sudo, монтирование home на nfs хранилке - всё работает, стролкнулся с проблемой монтирования сетевых шар cifs используя кеш Kerberos:

adm69@rosa82 ~ $ sudo mount.cifs --verbose //SRV.DC.TEST/TEST /opt -o"user=adm69,cruid=$USER,sec=krb5,domain=DC.test,multiuser,vers=2.0"
mount.cifs kernel mount options: ip=10.10.1.139,unc=\\SRV.DC.TEST\TEST,sec=krb5,multiuser,vers=2.0,cruid=1760801111,user=adm69,domain=DC.test,pass=********
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 убрать аргумент sec=krb5, монтирование происходит с вводом пароля:
adm69@rosa82 ~ $ sudo mount.cifs  --verbose //SRV.DC.TEST/TEST /opt    -o "user=adm69,domain=DC.test,multiuser"
Password for adm69@//SRV.DC.TEST/TEST:
mount.cifs kernel mount options: ip=10.10.1.139,unc=\\SRV.DC.TEST\TEST,multiuser,user=adm69,domain=DC.test,pass=********
adm69@rosa82 ~ $ df -h

Если только один аргумент sec=krb5 - ошибка
adm69@rosa82 ~ $ sudo mount.cifs  --verbose //SRV.DC.TEST/TEST /opt -o sec=krb5
mount.cifs kernel mount options: ip=10.10.1.139,unc=\\SRV.DC.TEST\TEST,sec=krb5,user=root,pass=********
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)

adm69@rosa82 ~ $ klist

Если проверить доступность шары smbclient с ключём -k (kerberos), в шару проваливаюсь:
adm69@rosa82 ~ $ smbclient -k //SRV.DC.TEST/TEST
Try "help" to get a list of possible commands.

Не работает ни под доменным пользователем, ни под root. Билет выписывается, кеш хранится в файле.

Есть кто сталкивался с данной проблемой?
Перейти на другой домен пока не получится, первое время будут существовать и Windows и Linux рабочие места с ActiveDirectory.
