Replace primary DC
Hi Adnan,
Your steps look correct.
There are no ?secondary? or ?primary? DCs. All equal except for FSMO roles.
http://samba.bigbird.es/doku.php?id=samba:fsmo-roles
You do not need to back up sysvol or idmap as they should be already synced with other DCs.

Switching roles between 2 DCs
Being a newbie to Samba 4 and OpenLDAP I am setting up a DC going
exactly by the rules, testing and taking my time. I got to the point
where I would switch, just testing, roles from DC1 to DC2 and vice
versa. Switching all roles from DC1 to DC2 was a piece of cake,
reswitching "domaindns" and "forestdns" to DC1 wasn't, though:
samba-tool fsmo transfer --role=domaindns -k

Keeping idmap in sync cross DC
Hi Guys,
I have run into a very interesting problem using GPO's on our DC's.
As you may (or may not) know, we have migrated to a pure Samba4 (Git stable
branch checkout) AD network. I can't be happier. *Kudos to the Samba team*
We are running to DC's, DC1 and DC2, both full fledged DC's, both running
CentOS 6.9, fully up to date.
For the sysvol partition I decided to run a

Hello James,
To your questions:
*"Are DC1 and DC2 in the same geographical location?"*
     Yes, they are in same location, & they are in the same subnet as well.
*"I'm also unclear from your message if you are still having password 
issues or not."*

Question about syncing idmap.ldb between Domain Controllers
Thanks. I sync sysvol every hour 9-5 and idmap daily.
I do not edit or create GPOs often so I guess that?s enough.
I wanted to make sure I had this article right :
http://samba.bigbird.es/doku.php?id=samba:sync-idmap.ldb
All the best.

samba4 replication issues | sam.ldb inconsistency
Hi all,
We seem to have some issues with our samba4 ad setup. I posted about 
this last week already but had received no replies at all so far. :-(
What is our situation:
two domain controllers (dc1 and dc2), one (separate) fileserver, all 
running sernet-4.1.7. From the workstations perspective, everything is 
running as it should, there appear to be no issues.
However: something in my

Hello James,
Even after setting the rfc2307 in smb.conf replication error continues 
and password change error continues. Error thrown while forcing 
replication is shown below.

Even after setting RFC, DC2 is not getting synced from DC1. Connection 
time out error comes.

Replicate with --full-sync error
Hi,
I tried to replicate two DC's (on test setup) with "--full-sync" option
but fails with error message below. I tried "--full-sync" because I
wonder if it has any effect on some diverged entries reported
by "samba-tool ldapcmp".
