[Samba] replicating sysvol with windows DCs

[Alex King]

I have samba4 set up as an AD DC, and it's working well.   It is one of 
3 Domain controllers in a domain, the other two being Windows 2008r2.  I 
followed https://wiki.samba.org/index.php/Join_a_domain_as_a_DC

One thing I that could be improved on the wiki is information about 
SysVol replication when there are Windows DCs as peers to samba. I've 
seen https://wiki.samba.org/index.php/SysVol_Bidirectional_Replication 
which hints some people have scripts set up to sync with windows DCs.  
Are there any pointers to information about this?

Cheers,
Alex
