Thank you Loui,

In the near future I am planning to install a second windows AD server 
for redundancy, so if one of them fails
the other one will take over. You mentioned that if I want more servers 
the AD backend is a better choice.
By "/more servers/" did you mean more samba storage servers or more DC's?

Is there going to be a problem when the time comes to install a second 
win.AD server for redundancy?
I am thinking of 3 servers. 2 running windows AD and 1 samba storage 
server. That's it, no more.

Many thanks for your help
