[Samba] Samba4 Secondary DC Replication Concerns

["David González Herrera - [DGHVoIP]"]

Hey there Paul,

Following up on my previous message I'm assuming that if you'll follow 
my advise of re-provisioning Samba, remember to *always* backup either 
using /usr/local/samba_backup script or making a tar out of your tdb 
files, because provisioning it again is a destructive non-recoverable 
procedure.

As I said if it's not a production system try re provisioning, but 
always as a rule of thumb have a backup handy just in case things go south.

Cheers.
