настроена авторизация пользователей сквида через самбу. все работает на ура... но есть проблема...
Собственно проблема токо в самбе... через какое-то время в логах winbind'a появляется такое:

Ну а потом происходит просто такое, на контроллере домена вылетает сервис, который связан RPC:

сталкивался ли кто с такой проблемой? может просто самба криво настроена?...
