error with configuring subdomain

[Sergey Leschenko]

Hello, I want to get the configuration of the central tree, the branches 
of which are replicated in the Multi-master mode with his subordinates 
DCs and back. For example:
There is a central dc.domain.local, which is the main DCs for the 
company (realm DOMAIN.LOCAL).
There dc.kiev.domain.local (realm KIEV.DOMAIN.LOCAL), 
dc.lviv.domain.local (realm LVIV.DOMAIN.LOCAL), which are the DCs for 
its branches.

I want that when changes are made to kiev.domain.local, so they 
replicated to DN: dc=kiev,dc=domain,dc=local on the main DC dc.domain.local.

I thought that this should be used:
samba-tool domain join domain.local SUBDOMAIN -Uadministrator 
-realm=DOMAIN.LOCAL -parent-domain=domain.local

but got an error:

Say configuration I want to get possible?
