LDAP Schema 2 Compatibility Mode and Calendar Server

Schema 2 compatibility mode is an interim mode between Schema 1 and Schema 2 native mode. Schema 2 compatibility mode supports both schemas and enables you to retain the existing two-tree design you already have. Schema 2 compatibility mode also assumes that you have installed Access Manager prior to installing Messaging Server.

Use Schema 2 Compatibility if you have existing applications that require Schema 1, but you also need functionality that requires Schema 2, for example, Access Manager, single sign-on, and so forth.

Note –

Schema 2 compatibility mode is provided as a convenience in migrating to the Schema 2 Native mode. Do not use Schema 2 compatibility mode as your final schema choice. The migration process from Schema 1 to Schema 2 compatibility mode and then finally to Schema 2 native mode is more complex that simply migrating from Schema 1 to Schema 2 native mode. See the Sun Java System Communications Services 6 2005Q4 Schema Migration Guide for more information.
