samba - Jun 2015 - ERROR: parent object not found for replicate child DC in forest

There is stand with AD forest contains DC with domain
company.local and DC with domain filial1.company.local (both on Windows
2003).

Our partner try to replicate domain
filial1.company.local from Windows DC to Samba AD DC 4.2.2 and get fatal
database error:

# samba-tool dbcheck --cross-ncs --fix
Checking 295 objects
ERROR: parent object not found for DC=filial1,DC=company,DC=local
Move object DC=filial1,DC=company,DC=local into LostAndFound?

There is check in dbchecker.py:
for DC=filial1,DC=company,DC=local
self.samdb.get_root_basedn() returns DC=company,DC=local

How I can fix this error?
