[Samba] Sysvol replication

[Jim Potter]

Hi Robert,

The sysvol share (or possibly AD userand and computers) is really 
pedantic about attributes. I've got it all working so that it looks fine 
(replication works by whatever means) but ADUC kicks up errors. For 
rsync I get permission errors (different uidnumbers for specific users 
and groups on different servers), but with gluster is says it can't set 
the permissions and dies. I haven't tried DRBD...

What you are proposing looks more like 1 active DC with a failover 
solution rather than having multiple DCs running simultaneously, right? 
I hadn't really looked at that... I was just following the MS approach 
of 'you need multiple DCs if you are doing anything serious' model. That 
would be wortha look in some scenarios, but where I am I've got ~850 
workstations in a school (so all log in within 5 minutes of each other 
at the start of each lesson) so the ability to add DCs until they can 
handle the load is pretty essential.

cheers

Jim
