[Samba] Kcc connection

[Christian Naumer]

Hello all,
we have upgraded our 4 DCs from samba 4.4.12 to 4.6.3. The setup is working fine and no errors were displayed during the upgrade.  After a day I noticed that the DC (dc1) holding the fsmo roles is missing one kcc connection (to dc3) in the output of samba-tool drs showrpl. Otherwise there are no errors displayed. On windows in the ADSites tool I see that the connection is missing and I can create it. This is also reflected in the output of samba-tool. 
The question is should this link be created automatically? What can I do to create it on the host in question ? 
All the DCs are at one site. 

Addition question. Searching for reason I found that in DNS there are two entries in _pdc one for dc1 and one for dc4 ( I transferred fsmo roles between them ones) I think there should be only one there. Am I correct? 

Thanks for your help. 

Regards

Christian
