Current System: GroupWise 2012 on SLES 11

Been setting up the High Security option for the Post Offices to use Active Directory LDAP and I am running into a logistics issue.

The issue is because I am using AD LDAP and not Novell LDAP. The LDAP Name Mappings are different between the two systems due to the account locations in the two trees. To make it work, I would need to add the AD LDAP Name Mapping into the GroupWise Object | Account | LDAP Authentication field. With over 3,800 users, this is a monumental task to manually add this field to each object.

Is there a script or a possible app to run to populate the AD LDAP Name Mapping for each user GroupWise object?

Any feedback and/or guidance is appreciated.
