[Samba] Replication Ok, or not?

[Michael Ray]

I just set-up replication this morning and saw a similar situation. 
I tested it by simply turning off my PDC and seeing what happened -- and everything worked just fine. 
I then also added a new user to this alternate DC, brought up the PDC, killed the alternate DC after a minute, and checked to see if I could find the new user in the db. And sure enough, the user was there. 

https://wiki.samba.org/index.php/Samba4/HOWTO/Join_a_domain_as_a_DC#Testing_Directory_Replication 

^ Gives a few ideas for testing replication and communication between DCs, but the output of your drs showrepl looks fine to my (admittedly inexperienced) eyes. 

As far as the NC error, I also saw that and found this: http://lists.samba.org/archive/samba-technical/2011-November/080379.html 

TL;DR: it's probably nothing -- if the tests for replication work, don't worry much about it.

I think that is just a bug. Not sure if its been reported yet or not though.
