For corporate and remote address books a corresponding xxx instance should exist in the personalstore.properties file. The value of db.xxx.urlmatch in personalstore.properties file should be assigned the value of bookremoteurl attribute present in defaultps.xml file.
To add a new remote address book, you need to add the following items:
Add a new book node in defaultps.xml file
Add a new xxx instance in personalstore.properties file.
Create a directory under WEB-INF/config to store the db_config.properties and xlate files.
The xlate files contains the field mappings between an LDAP schema and address book XML schema for a contact or group.
