Hi Samba Experts,
I have a small AD setup with two Samba DCs, both running Samba 4.7.4.
Since a few days, one of the DCs appears to replicate to itself.

On the affected DC2, "samba-tool drs showrepl" displays the 5 usual
directory nodes that are replicated:|
| Default-First-Site-Name\DC2|
|||DSA Options: 0x00000001|
|||DSA object GUID: 8acfcfcd-6d87-4fee-8dfd-d1c111fdb821|

|||and so on, the same for|

||||||||CN=Configuration,DC=ad,DC=mydomain,DC=ch
DC=DomainDnsZones,DC=ad,DC=mydomain,DC=ch||
and it displays
||||DC=ForestDnsZones,DC=ad,DC=mydomain,DC=ch
||||Default-First-Site-Name\DC2 via RPC
|||| DSA object GUID: 8acfcfcd-6d87-4fee-8dfd-d1c111fdb821
|||| Last attempt @ Sun Feb 25 16:12:35 2018 UTC was
successful
|||| 0 consecutive failure(s).
|||| Last success @ Sun Feb 25 16:12:35 2018 UTC
||||and
||||DC=DomainDnsZones,DC=ad,DC=mydomain,DC=ch
||||Default-First-Site-Name\DC2 via RPC
|||| DSA object GUID: 8acfcfcd-6d87-4fee-8dfd-d1c111fdb821
|||| Last attempt @ Sun Feb 25 16:12:39 2018 UTC was

i.e. this system apparently replicates to itself.
What's wrong with DC2? Beside this strange output it appears to work
correctly.DC1 does not show this behaviour.
