Uses of Directory Data

Open Directory makes it possible to consolidate and maintain network information

easily in a directory domain, but this information has value only if application and

system software processes running on network computers access the information.

Here are some ways in which Mac OS X system and application software use

directory data:

Â Login: Workgroup Manager can create user records in a directory domain, and these

records can be used to authenticate users who log in to Mac OS X computers and

Windows computers. When a user species a name and a password in the Mac OS X

and password. Open Directory uses the name to nd the user’s account record in a

directory domain and uses other data in the user record to validate the password.

Â Folder and le access: After logging in, a user can access les and folders. Mac OS X

uses other data from the user record to determine the user’s access privileges for

each le or folder.

Â Home folders: Each user record in a directory domain stores the location of

the user’s home folder. This is where the user keeps personal les, folders, and

preferences. A user’s home folder can be located on a computer the user always

uses or it can be located on a network le server.

Â Automount share points: Share points can be congured to automount (appear

automatically) in the /Network folder (the Network globe) in the Finder windows

of client computers. Information about these automount share points is stored in a

directory domain. Share points are folders, disks, or disk partitions you have made

accessible over the network.

Â Mail account settings: Each user’s record in a directory domain species whether

the user has mail service, which mail protocols to use, how to present incoming

mail, whether to alert the user when mail arrives, and so forth.

Â Resource usage: Disk, print, and mail quotas can be stored in each user record of

a directory domain.

Â Managed client information: The administrator can manage the Mac OS X

environment of users whose account records are stored in a directory domain. The

administrator makes mandatory preference settings that are stored in the directory

domain and override users’ personal preferences.

Â Group management: In addition to user records, a directory domain also stores

group records. Each group record aects all users who are in the group. Information

in group records species preference settings for group members. Group records

also determine access to les, folders, and computers.
