[Samba] AD replication problem "WERR_DS_DRA_ACCESS_DENIED" - need help debugging

We have 3 ADCs based on Samba-4.7.4 (compiled from source,internal DNS)/ 
CentOS7: dcdo1,dcnh1 and dcge1. dcge1 holds all FSMO roles. The 3 ADCs 
are on different locations connected via IPSec based VPN. No traffic is 
filtered out.

All 3 ADCs replicate fine except dcdo1 -->dcnh1. Symptom:

[root at dcdo1 ~]# samba-tool drs replicate dcnh1.ad.kdu.com 
dcdo1.ad.kdu.com dc=ad,dc=kdu,dc=com
ERROR(<class 'samba.drs_utils.drsException'>): DsReplicaSync
failed -

   File "/usr/lib64/python2.7/site-packages/samba/drs_utils.py", line

     raise drsException("DsReplicaSync failed %s" % estr)

[Samba] AD replication problem "WERR_DS_DRA_ACCESS_DENIED" - need help debugging

There is additional info in the logs of the source DC (dcdo1, log level 
2, manually triggered another replication):

seems to exist.

Any ideas?
