Can I join windows server 2008 r2 as secondary domain controller to UCS?

I have UCS 4.1 with installed Active Directory-compatible Domain Controller.

As described at I can join 2008 r2 as domain controller to samba domain.

But in UCS documentation I cann’t found any info about it.
Help, please.


maybe it is possible but we don’t support it at the moment:

See our manual

Microsoft Active Directory domain controllers cannot join the Samba domain. This functionality is planned at a later point in time.
