Thank you, William!

Are you running RHDS8?  It is quite old...  I'd recommend the latest 
version which is RHDS 10.

Retro changelog is a separate plug-in.  Despite of the name "retro", it 
is still useful to store the change logs in the database independent 
from new/old replications.

    dn: cn=Retro Changelog Plugin,cn=plugins,cn=config
    objectClass: top
    objectClass: nsSlapdPlugin
    objectClass: extensibleObject
    cn: Retro Changelog Plugin
    nsslapd-pluginPath: libretrocl-plugin
    nsslapd-pluginInitfunc: retrocl_plugin_init
    nsslapd-pluginType: object
    nsslapd-pluginbetxn: on
    nsslapd-pluginEnabled: off
    nsslapd-pluginprecedence: 25
    nsslapd-plugin-depends-on-type: database
    nsslapd-plugin-depends-on-named: Class of Service

cn=changelog5,cn=config is the changelog being used in MMR -- 
cn=Multimaster Replication Plugin,cn=plugins,cn=config.
