Samba 4 in RHEL 7.0 without AD capability?

Hi guys,
can some of your RH guys confirm or shed some light on this? I just stumled on some posts on samba lists today complaining about it.

Is that right? RH doesn't support Samba 4 AD? So to say, we have only possiblity for old 'classic' NTv4 domain on SAmba 4 on RHEL 7 so far?

I dont have test machine handy for RHEL 7 handy today., but i'm gonna try it soon

thanks for any info,
