Собственно сие (по началу без кербероса и с security = domain ) работало достаточно длительное время. Потом враз перестало. samba пользуется как бекап сервер и сервер для всяких дистрибутивов. Соответственно никто на нём практически не сидит. И вот начали валиться репорты, что бекапы не идут. из всех ошибок нарылась только эта:

К сожалению самостоятельные поиски решения ответа не дали. Может кто сталкивался с подобным и подскажет?
