Hello list,

I am testing Samba 4.8.0rc3 and see following output every drepl-Service 

DRS replication add DN of ad1894a9-07f8-4ae2-8e5c-2a15ed9ed8b3 is 
CN=BUILDHOST,OU=Domain Controllers,DC=samdom,DC=local
ldb: ../lib/ldb/ldb_tdb/ldb_index.c:1837: unique index violation on 
@IDXDN in CN=BUILDHOST,OU=Domain Controllers,DC=samdom,DC=local, 
conficts with ɟܬoѢNo𮭗k in @INDEX:@IDXDN:CN=BUILDHOST,OU=DOMAIN 
Replicated 89 objects (163 linked attributes) for DC=samdom,DC=local
dreplsrv_op_pull_source(WERR_OK) for DC=samdom,DC=local

It is always 89 objects with the same number of attributes.

DC is an RODC joined with Version 4.6.x(or 4.5.x I don't know anymore) 
and then upgraded to 4.8.0rc3 in place. There is no other errors or 
warnings I can see now.

I saw message like this on other domain, where I joined RODC with 4.7.0 
and than upgraded in place by 4.8.0rc3.

Is it an error or warning? What should I do with such issues?
