Schema Definition

The schema is the set of rules that describe the data that can be stored in the directory. It defines the type of entries, their structure and their syntax. The schema can be modified and extended, though certain objects and attributes cannot be changed.

The schema definition is stored in two files in the configuration directory /etc/opt/SUNWconn/ldap/current:

• dsserv.oc.conf defines the object classes. These specify the types of entries permitted, their superior object class, and their mandatory and optional attributes.

• dsserv.at.conf contains attribute definition information:

  • An oid representing the attribute

  • The attribute syntax, specified using a keyword

  • Alternate names for some attributes

  • The keyword naming for attributes that are naming attributes

  • The keyword single for single-valued attributes

For the exact format of an LDAP attribute definition, refer to the dsserv.at.conf(4) man page.
