However, as you can see I still get the

syncprov overlay entry the lines disappear.
But I can understand that it should only be done if you have an acceslog.
So is it really necessary to go through all the objects in the database
every time you modify a single record when you have a mmr setup?
It just seems like a lot of information written to the log and a lot of
work every time a single record is modified.
Do you have a session log configured?

No I didn't. But now you mentioned it I have tried to add
olcSpCheckpoint and olcSpSessionlog to my syncprov overlay so it looks
something like this
/etc/ldap/slapd.d/cn=config/olcDatabase={1}mdb/olcOverlay={0}syncprov.ldif:
dn: olcOverlay={0}syncprov
objectClass: olcOverlayConfig
objectClass: olcSyncProvConfig
olcOverlay: {0}syncprov
olcSpCheckpoint: 100 10
olcSpSessionlog: 100
structuralObjectClass: olcSyncProvConfig
Now the 'nonpresent_callback' lines have disappeared, but instead I see
a lot of entries like 'dn_callback : entries have identical CSN'. I
haven't had time to look into how to fix that. But I don't know if the
olcSpCheckpoint and olcSpSessionlog values I have added makes sense.
