14 Chapter 1 Directory Service Concepts
Apple has built an open, extensible directory services architecture, called Open
Directory, into Mac OS X and Mac OS X Server. A Mac OS X client or Mac OS X Server
computer can use Open Directory to retrieve authoritative information about users and
network resources from a variety of directory services:
LDAP service on a Mac OS X Server system
NetInfo service on a computer with Mac OS X or Mac OS X Server
Active Directory service on a Microsoft Windows server
OpenLDAP or other LDAP service on a third-party server such as Sun One or Novell
eDirectory
NIS on a UNIX server
BSD configuration files stored locally (not retrieved from a server)
Mac OS 9 and Mac OS 8 managed clients also use Open Directory to retrieve some user
information. For more information, see the Macintosh Manager chapter in the user
management guide (available at www.apple.com/server/documentation/).
In addition, Mac OS X and Mac OS X Server can use Open Directory to discover network
services, such as file servers, that make themselves known with the Rendezvous,
AppleTalk, SLP, or SMB service discovery protocols.
The Open Directory architecture also includes authentication service. Open Directory
can securely store and validate the passwords of users who want to log in to client
computers on your network or use other network resources that require
authentication. Open Directory can also enforce such policies as password expiration
and minimum length. Open Directory can also authenticate Windows computer users
for domain login, file service, print service, and other Windows services provided by
Mac OS X Server.
