samba - Sep 2015 - Verify that user replication between master and slave through the logs?

Hello guys,

On my other e-mail does not properly explain what I was looking for.

I made the data replication between two domain controllers Samba 4. At this
point everything is okay. When I create a user, for example in master,
after a few seconds the slave already have this user.

What I want to know is how can I verify that user replication between
master and slave through the logs?

You shouldn't need to :-)
As soon as the source DC (note: you don't have a master DC and a slave 
DC, you just have two DCs) is changed, replication should kick in and 
the users object should be replicated to any other DCs.

Have a look here: 
https://technet.microsoft.com/en-us/library/cc772726%28v=ws.10%29.aspx

It may help you understand just how replication works.

It may also have escaped your notice that you can create users on any DC 
and they will be replicated to any other DCs, the only way to tell which 
DC a user was created on is by looking at the users RID, each DC is 
allocated a range by the RID master.

I guess samba-tool can also reassure you when used as:
samba-tool drs showrepl

Another way to be very sure if you prefer burn CPU rather digging into logs
is:
samba-tool ldapcmp dc1 dc2 domain -U administrator

Where "domain" stand here to compare only domain part of Samba AD DB
(ie
not DNS, config, schema...)

Thanks to Rowland to show me that (these?) command(s) weeks ago :)
