Help removing old replicas

Open Directory Master running 10.6.8 shows old replicas in the Replica Tree.

I've run:

sudo slapconfig -removereplica -(ipaddress) diradmin

I've edited the DSLADPv3PlugInConfig.plist in /Library/Preferences/DirectoryServices

In WGM, with Inspector enabled, I've edited the list of ldapreplicas and the KerberosClient

(XMLPList and dsAttrTypeNative:apple-xmlplist.)

Decommissioned replicas are still in the list.

Does anyone know how to remove these replicas that are no longer is use from Server Admin?
