[Samba] samba-tool drs showrepl not reporting last attempt/success time correctly

I'm having a strange"samba-tool drs showrepl" output and I don't know
where to start to fix it.
My environment:
- SRVWIN: Win2008R2 DC server
- SRVSAMBA: Samba 4.7.6 DC on Ubuntu 18.04 Server
- SRVSAMBA2: Samba 4.7.6 DC on Ubuntu 18.04 Server
To test AD replication I've created an user object on SRVWIN and it
appears on both SRVSAMBA and SRVSAMBA2 (checked with ADUC from SRVWIN).
Then I changed the user object on SRVSAMBA and changes are reflected on
both SRVWIN and SRVSAMBA2.
Finally I've deleted the user object from SRVSAMBA2 and it disappeared
on all DCs.
I'm supposing replication works correctly, but "samba-tool drs showrepl"
on Samba servers shows something strange:
INBOUND NEIGHBORS items are all ok while OUTBOUND NEIGHBORS to/from
Samba servers shows "NTTIME(0)" instead of the expected attempt/success
dates.
This is the output of "samba-tool drs showrepl" run on SRVSAMBA.
Running it on SRVSAMBA2 gives the same output, just swap SRVSAMBA with
SRVSAMBA2.
Is this expected?
How could I fix it?
Thanks
Claudio
