Добрый день!

У меня настроен samba server 4 в роли ROLE_DOMAIN_MEMBER (centos 7), довольно долгое время работал нормально. Внезапно перестал запускаться winbind, ошибка почему-то не гуглится.

Конфиг самбы:
[global]
        workgroup = DOMAIN
        realm = DOMAIN.LOCAL
        security = domain
        template shell = /bin/bash
        winbind separator = +
        winbind enum users = Yes
        winbind enum groups = Yes
        winbind use default domain = Yes
        winbind nss info = rfc2307
        winbind refresh tickets = Yes
        idmap config domain : schema_mode = rfc2307
        idmap config domain : range = 10000-99999
        idmap config domain : backend = rid
        idmap config * : range = 10000-99999
        idmap config * : backend = tdb

На сервере AD (windows 2012) компьютер smbserver прописывается если удалить и снова подключить, в DNS присутствует. Ошибка "PANIC (pid 8230): Could not find our domain" не гуглится почему-то совсем. Подскажите, пожалуйста, в какую сторону смотреть.
