Administering Enterprise Domains
A database can use a schema mapping to share one database schema between
multiple directory users. The schema mapping is a pair of values: the base in the
directory at which users exist, and the name of the database schema they will use.
You can use the Database Schema Mappings tabbed window to manage database
schema mappings—when a database is selected under a realm in the main
application tree or when a domain is selected. If a domain is selected, these
mappings apply to all databases that are members of the enterprise domain.
Therefore, each database in the enterprise domain must have a schema of the same
name used in the mapping for that mapping to be effective on that database. This
window contains a list of database schema names, directory DNs, and mapping
types (Figure 13–8):
