Chapter 2 Upgrading Mac OS X Server Version 10.3 21
Groups
If you want groups to use new version 10.4 features such as nesting and stricter
membership checking, upgrade group records using Workgroup Manager.
To upgrade a group record:
1 Open Workgroup Manager.
2 Open the directory that contains the groups of interest.
3 Select one or more groups and click “Upgrade legacy group.”
4 Click Save.
Directory Services
After upgrading, you may want to convert a shared NetInfo directory to LDAP. See the
Open Directory administration guide for details about the advantages of using LDAP
and how to use Server Admin to conduct the conversion.
You can also convert to Open Directory authentication from a different authentication
strategy. For example, if any of the users in your upgraded server are configured to be
authenticated using Authentication Manager, you can change their settings to Open
Directory authentication. Authentication options and instructions appear in the Open
Directory administration guide.
If you want to enable Kerberos for an Open Directory master on which it’s not enabled,
you can use the following command, which maintains existing passwords and adds
them to a new KDC.
slapconfig -kerberize
If you have user accounts with crypt passwords and you don’t Kerberize them using the
command above, you can use Workgroup Manager or the NeST command to use an
Open Directory password:
 To use Workgroup Manager, open the application and access the directory in which
the user account resides. Authenticate as domain administrator, then select a user
with a crypt password. Click Advanced, choose Open Directory from the User
Password Type pop-up menu, click Basic, specify a new password, and click Save.
 To use the NeST tool, open the Terminal application and type:
NeST -convertuser <user-name> <domain-administrator-name>
For more information about NeST and slapconfig, see their man pages.
NetBoot Images
NetBoot images created using version 10.2 and 10.3 can be reused following the
upgrade installation.
To manage Netboot images, you use System Image Utility, which replaces Network
Image Utility during the upgrade installation.
