118 Chapter 8 Working with Users and Groups This will prompt you f or your diradmin passwor d, which is much more secure than putting the password in the command y ou are sending. See the dseditgroup man page for more inf ormation. Creating a Group F older A group folder facilitate s the sharing of files between members of a group .
Chapter 8 Working with Users and Groups 119 Impor ting Users and Groups Y ou can use dsimport to import user and group accounts. into a folder . The dsimport tool permits logging at three levels with the -l swit ch. Y ou can use the dsimport tool to import any number of records from a flexible te xt–delimited file.
120 Chapter 8 Working with Users and Groups Open Director y supports up to 200,000 records . F or a local NetInfo directory , make sure the file contains no more than 1 0,000 records. 2 Log in as the administrator of the dir ector y domain you want to import accounts into .
Chapter 8 Working with Users and Groups 121 Â List of attributes F or user accounts , the list of attributes must include the f ollowing , although you can omit UID and PrimaryGroupID if you specify .
122 Chapter 8 Working with Users and Groups Matt Mitchell:/bin/tcsh As these examples illustrate , you can use the prefix dsAttrTypeStandard: when referring to an attribut e, or you can omit the prefix. When y ou use W orkgroup Manager to export charac ter-delimited files , it uses the prefix in the generated file .
Chapter 8 Working with Users and Groups 123 Setting P ermissions T o control acce ss to your information, Mac OS X automatically sets permissions for disks, folders, and files. Y ou can only change permissions to items that you own. Be sure that the default permissions are appr opriate.
124 Chapter 8 Working with Users and Groups  The follo wing file (-) displays read , write , and executable permissions for owner (rwx), but no permissions for group (---) or others (---): -rwx-----.
Chapter 8 Working with Users and Groups 125 This command affects the permissions on files and f olders created by programs that respect the Mac OS X NSUmask settings. Programs should follo w the value set for NSUmask, but there is no guarant ee that they will.
126 Chapter 8 Working with Users and Groups Changing the Owner Use the chown tool to change the owner of a file or f older . $ chown username fileorfolder T o change the owner of file1 to the user jdoe: $ chown jdoe file1 See the chown man page for more inf ormation.
Chapter 8 Working with Users and Groups 127 Securing the Root Accoun t Mac OS X Ser ver includes a root account like other UNIX-based systems . Initially , its password is set to that of the first administrat or account. Direct root login should not be allowed , because the logs cannot identify which administrator logged in.
128 Chapter 8 Working with Users and Groups Note: There is a timeout v alue associated with the sudo tool. This value indicat es the number of minutes until the sudo t ool prompts for a passwor d again.
Chapter 8 Working with Users and Groups 129 5 If the computer did start up in single-user mode, restart the computer by issuing the command reboot . T hen repeat the previous steps f or putting the computer into command mode.
