Directory Services Framework#
In a more general sense, Open Directory can describe the plugins model used by Directory Utility and the directory services framework in Mac OS X and Mac OS X Server. This could be thought of as analogous to the Name Service Switch
systems of some other Unix-like operating systems. When connected to a directory system, a Mac OS X client or Server can authenticate users, lookup contacts, perform service discovery and name resolution with the following types of directories:
Apple Computer OID
- Authentication & Contacts
- Service Discovery & Name Resolution
is used to define their custom LDAP Schema
