FreeBSD equivalent of Microsoft DFS

for all: MS DFS = MS Distributed File system is NOT a FS
it's a shared directory on a drive that is replicated via AD mechanism to 1 or more locatations
If setup correctly DFS can have 2 or many more servers, and to replicate it only needs a partner server to replicate with.
all other servers can be turned off .. its neither a ring or a star shaped network. (not 100% true but makes explaining a lot easier)
In Freebsd that woud be a CIFS or NFS share that is synced over 1 or more sites (without bandwith control )
The only issue if you want to replicate this within Freebsd is how to setup the sync process for more then 3 hosts.
And more specific if 1 file gets edited on to seperate "servers" and replicated to a 3rd server, what happens then?
Of course such a write action "when it happens" is very very small chance.
IF you want to use FreeBSD as a file server for a windows enviroment (with ZFS) you can do 2 things
1) use ZFS and make a ISCSI -disk (istgt port for now) and connect the ISCSI disk to a Virtual server with a windows "server" host
2) use ZFS + SAMBA, configure samba to use the AD information to give access (Single Sign On)
The first one is the easiest & fastest way however it will cost you performance compared with the second solution.
The most difficult is to have samba connecting to a AD enviroment without any alterations on the windows machines/ad
and kerberos. However SAMBA & AD are reported to have a love hate relation ship working together, and can break
