11. Schema Specification
This chapter describes how to extend the user schema used by slapd(8). The chapter assumes the reader is familiar with the LDAP/X.500 information model.
The first section, Distributed Schema Files details optional schema definitions provided in the distribution and where to obtain other definitions. The second section, Extending Schema, details how to define new schema items.
This chapter does not discuss how to extend system schema used by slapd(8) as this requires source code modification. System schema includes all operational attribute types or any object class which allows or requires an operational attribute (directly or indirectly).
