Chapter 1 Directory Services with Open Directory 19
Other application and system software processes can also use the user account
information stored in directory domains. When someone attempts to log in to a
Mac OS X computer, the login process uses Open Directory services to validate the
user name and password:

A Historical Perspective
Like Mac OS X, Open Directory has a UNIX heritage. Open Directory provides access to
administrative data that UNIX systems have generally kept in conguration les, which
require painstaking work to maintain. (Some UNIX systems still rely on conguration
les.) Open Directory consolidates the data and distributes it for ease of access and
maintenance.
Data Consolidation
For years, UNIX systems have stored administrative information in a collection of les
located in the /etc directory, as show in the following illustration.
UNIX processes
/etc/master.passwd
/etc/hosts
/etc/group
This scheme requires each UNIX computer to have its own set of les, and processes
that are running on a UNIX computer read its les when they need administrative
information.
