Samba 4 (on a NAS) as Domain Controller across two sites
I have a client with two offices. One has about 30 users and the other about 15.
They have Server 2003 at one site and a workgroup at the other. All Win 7 and Win 8.
They only use basic file/printer sharing.
I'm contemplating using a NAS running Samba 4 as a domain controller and doing away with Server 2003.
I would install a NAS at each site and a VPN between sites.
99% of the files they need to access will be on the local NAS. Occasionally they will need to access a document on the remote NAS. I don't want to replicate data between the NAS's.
Should I have both sites on the same domain or two separate domains?
Should both sites be on the same subnet or different subnets?
Should I set up one NAS at the Active Domain Controller and the other as a Secondary Domain Controller?
What NAS devices should I consider for this?
If anyone has actually done this I would be interested in hearing about your experience.
