монтирование файловой системы DFS с удаленными общими ресурсами в это на Arch Linux

У меня ноутбук подключился к домену AAA. Имейте два сервера пространства имен DFS, которые также являются AD DC с Win Server 2012 R2. NAS - это сервер Synology с включенным CIFS / присоединенным доменом.

Серверы:

• dc1.domain1.local - ip 10.8.0.3
• dc2.domain1.local - ip 10.8.0.27
• nas1.domain1.local - ip 10.8.0.7
• laptop.domain1.local - 10.91.0.2

До недавнего времени все настройки работали. (не знаю, что произошло, обновление ядра? или Центр обновления Windows).

[sssd]
domains = domain1.local
config_file_version = 2
services = nss, pam

[domain/domain1.local]
ad_domain = domain1.local
krb5_realm = DOMAIN1.LOCAL
realmd_tags = manages-system joined-with-adcli
cache_credentials = True
enumerate = True
id_provider = ad
default_shell = /bin/bash
fallback_homedir = /home/%d/%u
krb5_lifetime = 1h
krb5_renewable_lifetime = 1d
krb5_renew_interval = 60s
ldap_id_mapping = True
krb5_store_password_if_offline = True

includedir /var/lib/sss/pubconf/krb5.include.d/
[logging]
 default = FILE:/var/log/krb5libs.log

[libdefaults]
 dns_lookup_realm = true
 dns_lookup_kdc = true
 ticket_lifetime = 24h
 renew_lifetime = 7d
 forwardable = true
 clockskew = 300
 rdns = false
 default_ccache_name = KEYRING:persistent:%{uid}

/etc/request-key.d/cifs.spnego.conf

create  cifs.spnego    * * /usr/bin/cifs.upcall -t %k

Я пытаюсь смонтировать общий ресурс с помощью

mount -t cifs -o sec=krb5,user=$USER,cruid=$USER,uid=$USER //dc1.domain1.local/namespace1 /mnt/mp1

Я могу пойти в / mnt / mp1. Но я не могу получить доступ к чему-либо, например //dc1.domain1.local/namespace1/share1 который находится на сервере Synology (/mnt/mp1/share1).

Журналы на ноутбуке во время монтирования:

[   54.894236] No dialect specified on mount. Default has changed to a more secure dialect, SMB2.1 or later (e.g. SMB3), from CIFS (SMB1). To use the less secure SMB1 dialect to access old servers which do not support SMB3 (or SMB2.1) specify vers=1.0 on mount.          
[   55.036042] CIFS VFS: Autodisabling the use of server inode numbers on new server.
[   55.036046] CIFS VFS: The server doesn't seem to support them properly or the files might be on different servers (DFS).
[   55.036049] CIFS VFS: Hardlinks will not be recognized on this mount. Consider mounting with the "noserverino" option to silence this message.

При вводе / mnt / mp1 / share1 я получил:

Обратите внимание, что он запрашивает билет для другого хоста что это разрешено для IP-адреса. (10.8.0.7 - хост nas1.domain1.local).

Есть идеи, где искать ответ?
