Hi

I've encounter a problem in OpenLDAP 2.4.16 on 2 LDAP servers system setup with syncrepl multimaster and all data are synchronized. If server A is down and LDAP entries (leaf or subtree) are deleted on server B, when server A comes up, those LDAP entries are not removed from server A by syncrepl. If LDAP operations are done on either servers while both are up, syncrepl correctly propagates them to the other server.

Below are the slapd.conf files for both server A and B. Is there something wrong with the way they are configured or is this a known issue?

Thanks in advance.
