you can install adconnect on a windows domain member, it will sync your 
groups and users. If you want to sync password with adconnect you'd need 
to install it on the DC which is obviously a no go on a samba-ad linux 

You can join a win2k12 AD to your Samba domain specifically to run 
ADConnect. It would need to be firewalled so client desktop don't 
connect to that Microsoft Domain Controller. Beware of Microsoft 
internal firewall which handles icmp-unreachable in an artistic way, it 
is far better to have a linux firewall with REJECT and no DROP.

ADconnect can push a pdkdf2 derivative of the ntlm password in AD, but 
there is no published API to use. The only published api to push a 
password change needs the clear text password... So if you want to push 
from your Samba-AD you are stuck to keep a clear text version with Samba 
implementation of reversible crypto using GPGME and push it through the 
correct API.

I don't think there is any difference between Samba-AD or MS-AD...
> And what do I need to keep them in sync?
