Samba4x NT4 Style Primary Domain Controller and BDC on the rhel 7

Hi
I would like to know if rhrel 7 supports active directoy with PDC and bdc.

If not what do you recommends to setup Samba4x NT4 Style Primary Domain Controller and BDC on the rhel 7.

DO you have an example using samba4x PDC and BDC for rhrel7.

Thanks
