Проблема с zentyal ldap master и zentyal ldap slave + samba

Нашел решение проблемы при связке Zentyal ldap master и Zentyal ldap slave + samba. Суть ошибки заключалась в том, что slave c мастером соединялись нормально, но при попытке настроить на slave сервер пользователя (к примеру чтоб дать ему права администратора в домене поднятом на samba) вываливалась ошибка:

После долгих мучений и поиска решений спасло следующее:
на сервере ldap slave + samba от rootа выполнил скрипт  /usr/share/zentyal-users/rejoin-slave после чего все завелось.
