For the Samba 'classic/nt4-like' mode just removing the 'domain master = no' makes it a PDC. You can even have multiple PDCs as long as they can't see each other over netbios, the protocol is so simple it doesn't really matter (unlike AD).

Hi Andrew, Thank you for that. So it doesn't matter if I have TDB as my DB? Also, how do I replicate the data? Copy and paste ? /vat/lib/samba ,/private , passwd and group files?

Hi Andrew, I've setup a new Samba 4 box (sam4dc) on Ubuntu 14.04 with Samba 4.3.11. I have the following Just to clarify, sam3DC is the current DC with samba 3.6.3 smb.conf [global] workgroup = STEST netbios name = Sam4DC password server = Sam3DC (This is the current DC) security = user resolv.conf nameserver = 192.168.10.1 (IP of Sam3DC) I can ping the sam3dc from the sam4dc box using fqdn. When I try to join sam4dc into stest domain I get: net rpc join -U dadmin cannot join as standalone machine If I add the server role = member server , I get the same error message. If I add the security = domain , it asks me DO you really want to join an Active Directory Domain. If I put the password in, I get smb_signing_good: BAD SIG : seq 1 Do I copy the smb.conf file from sam3dc and change the bit about domain master = no ? Or do I have join the machine to the domain as DC using server role = DC in smb.conf?

Copy and paste ? /vat/lib/samba ,/private , passwd and group files?I did assume you were using LDAP. If you just copy the data then you will naturally not get any updates as there is no replication protocol, so it is less of a BDC and more of a migration route.
