Coexistence Manager for Notes (CMN) - Directory Connector can be used to write to a secondary Domino address book, using Domino Directory Assistance (DA) to direct LDAP writes to a selected address book.
Note: For assistance with creating a secondary address book, reach out to Domino support for help.
The documentation contains the up to date information on the steps to preparing this.
Note: A LDAP document will also need to be created for the lookup to route properly within Domino.
