Samba4 production - what is possible

[Martin Hochreiter]

Hi!

I want to try Samba4 instead Samba3 on my little company.
As i do not really have an overview how far the development really
is (i know it is still alpha but almost stable) - i just want to
state whate I need and ask you to tell me if thats possible (please :) ):

client (win7):
domain join, machine+user login/logout, password change, hold/serve  
group/user db

server:
use of 2 samba4 dc's for 2 vpn connected sites ... replication between  
the 2 servers,
File serving (hold the network share)

Is that possible yet?

regards
martin
