24 Chapter 1 User Management Overview
Server Administration
Server administration privileges determine the powers a user has when logged in to a
particular Mac OS X Server. For example:
• A server administrator can use Server Admin and can make changes to a server’s
search policy using Directory Access.
• A server administrator can see all the AFP directories on the server (from a computer
other than the server), not just share points.
When you assign server administration privileges to a user, the user is added to the
predefined group named “admin” in the local directory domain of the server. Many
Mac OS X applications—such as Server Admin, Directory Access, and System
Preferences—use the admin group to determine whether a particular user can perform
certain administrative activities with the application. The primary Administrator
(“admin” user) is user ID 501 in the server's local directory.
Local Mac OS X Computer Administration
Any user who belongs to the group “admin” in the local directory domain of any
Mac OS X computer has administrator rights on that computer.
Directory Domain Administration
In Mac OS X Server, when you create a directory domain, a domain administrator
account is also created and added to the admin group in the domain. The UID of the
domain administrator defaults to 1000 when the account creation dialogue appears, at
which time you also have to set the name and password. The domain administrator
account is also a server administrator account, but the server administrator is not a
domain administer by default. Each directory has a separate domain administrator
account and a domain administrator can create additional administrators in the same
domain.
You can allow certain users to manage specific accounts. For example, you may want to
make a network administrator the server administrator for all your classroom servers,
but give individual teachers the privileges to manage student accounts in particular
directory domains. Any user who has a user account in a directory domain can be
made a directory domain administrator (an administrator of that domain).
You can control the extent to which a directory domain administrator can change
account data stored in a domain. For example, you may want to set up directory
domain privileges so your network administrator can add and remove user accounts,
but other users can change the information for particular users. Or you may want to
designate multiple administrators to manage different groups.
When you assign directory domain administration privileges to a user, the user is
added to the admin group of the server on which the directory domain resides.
