On the replication it says: "no such object". And that's the problem I
want to fix.

So far I know the ACL's are correct. This system works many years with
many Linux clients, now they also want Windows. On the location of the
master, they allready have a few Windows PC's for some years, and the
authentication works fine.

I expect they don't match ;-)

It will be a only in cn=config.

This is the way I create a LDAP admin:
cat <<EOF >slapd-database.ldif
dn: olcDatabase={1}hdb,cn=config
changeType: modify
replace: olcDbConfig
olcDbConfig: {0}set_cachesize 0 2097152 0
olcDbConfig: {1}set_lk_max_objects 1500
olcDbConfig: {2}set_lk_max_locks 1500
olcDbConfig: {3}set_lk_max_lockers 1500
olcDbConfig: {4}set_flags DB_LOG_AUTOREMOVE
replace: olcRootPW
ldapmodify -v -Y EXTERNAL -H ldapi:/// -f slapd-database.ldif
