[Samba] outbound replication of newly added DC not working

[Andreas Oster]

Hi all,

I have just added a DC to our existing AD. Join did work without any
error messages but now I have recognized that only inbound replication
from old DCs is working outbound list is empty.

Samba version is: Version 4.2.0pre1-GIT-cff0f8e

here is the output of samba-tool drs showrepl:

( I have replaced domain and DC names in the output text !)


Does anybody know how to fix this issue and get outbound replication to
work ?

I have already tried to demote and re-join the new DC, but this did not
help. I have also checked the DNS entries and those seem to be OK.

Thank you for your kind help

best regards

Andreas
