110 Chapter 8 Working with Users and Groups
To create a home folder for users in the local domain:
$ sudo createhomedir [(-a|-l|-n
domain
)] -u
uid
You can also create a user’s home folder using the serversetup tool.
To create a home folder for a particular user:
$ sudo /System/Library/ServerSetup/serversetup -createHomedir
uid
The command displays a 1 if the user ID you specify doesn’t exist.
Mounting a User’s Home Folder
You can use mnthome to mount a user’s home folder. The mnthome tool unmounts the
AFP (AppleShare) home folder that was automounted as guest, and remounts it with
the correct privileges by logging into the AFP server using the current user name and
password.
To mount a user’s shared home directory on an AFP server:
$ mnthome -p
password
See the mnthome man page for more information.
Administering Group Accounts
A group is simply a collection of users who have similar needs. For example, you can
add all users with a particular task 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 the group. Information in group accounts is used to help
control user access to folders and files. Individual users may belong to multiple groups,
depending on their access needs.
A group can be nested within 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 at login time.
