[Samba] samba4 PDC to BDC file replication

[C Waddy]

Hi Greg,

Thanks for the info, its a tough one. I was hoping the msdsf would
replicate data but it appears it doesnt appear to or am i missing something?

I used a program in the past called File replication pro on Suse/novell
 and it worked. I haave emailed their support and asked if it will work in
our situation.

I am going to give it a go in the Samba4 test environment over the weekend,
ill let you know if it works.
