Chapter 1 User Management Overview 25

Users and Managed Users

Depending on how you set up your server and your user accounts, users can log in

using Mac OS 9 and Mac OS X computers, Windows computers, or UNIX computers and

be supported by Mac OS X Server in their work.

Most users have an individual account used to authenticate them and control their

access to services. When you want to personalize a user’s environment, you define user,

group, or computer preferences for that user. The term managed client or managed user

designates a user who has administrator-controlled preferences associated with his or

her account. Managed client is also used to refer to computer lists that have preferences

defined for them.

When a managed user logs in, the preferences that take effect are a combination of the

user’s preferences and preferences set up for any workgroup or computer list he or she

belongs to. See Chapter 9, “Managing Preferences,” on page 135 for managed user

information.

Guest Users

You may want to provide services for individuals who are anonymous; that is, they can’t

be authenticated because they don’t have a valid user name or password. These users

are known as guest users.

With some services, such as AFP, you can specify whether to let guest users access files.

If you enable guest access, users who connect anonymously are restricted to files and

folders with permissions set to Everyone. The guest user account is used when no

matching user record is found during authentication.

Groups, Primary Groups, and Workgroups

A group is simply a collection of users who have similar needs. For example, you can

add all English teachers to one group and give the group permission to access certain

files or folders on a volume.

Groups simplify the administration of shared resources. Instead of granting access to

various resources to each individual who needs them, you can add the users to a group

and then grant access to everyone in the group.

Information in group accounts is used to help control user access to directories and

files. See “Directory and File Access by Other Users” on page 30 for a description of how

this works.

Furthermore, groups can be nested within groups. For example, a group can be a

member of another group. A group that contains another group is called a parent

group, and the group that is contained is called a nested group. Nested groups are

useful for inheriting access permissions and managed preferences at login time.
