[Samba] SPN duplicates causing schema errors -> replication failures

Can anyone tell me why I'm often getting duplicate SPN's like this 
(excerpt from 'samba-tool ldapcmp'):

b'WSMAN/Servername', b'WSMAN/servername'

Every couple of months, I have to manually delete one of these entries 
using 'ADSIEdit'.

Until I do this, I get replication errors between my Samba and Windows 
2012 servers.

Here's my setup:

  * two Windows 2012R2 AD controllers
  * one Samba 4.12.5 AD controller
  * schema version:  69
  * functionnal level:  2008R2

Thank You!
