Hello Andrew,
changing/adding the objectClass values did work. The only remaining
difference is the objectCategory. In my setup I have:
objectCategory: CN=Top,CN=Schema,CN=Configuration,DC=novanetwork,DC=loc
but I think it should be:
objectCategory:
CN=Domain-DNS,CN=Schema,CN=Configuration,DC=novanetwork,DC=loc
is this something that needs to be fixed ?
best regards
Andreas
