Chapter 9 Managing Preferences 137

The cached preferences can help you manage local user accounts on portable

computers even when they’re not connected to a network. For example, you can create

a list of computers you want to manage, and then manage preferences for the

computer list. Next, you can make these computers available to groups and then

manage preferences for the groups. Finally, you can set up local user accounts on the

computers. Now, if a user goes offline or disconnects from your network, he or she is

still managed by the computer and group preferences in the cache.

When you make a change that affects cached information for an account, Workgroup

Manager sets a “flag” in Open Directory to indicate that change. When a user logs in,

the client updates automatically.

Note: When you modify an account or preference setting, the preferences cache is

updated automatically. New preferences take effect at the user’s next login/logout

cycle. If the user is already logged in while away from the network, they must perform

a logout and re-login in order to update the preference cache.

Updating the Managed Preferences Cache at Intervals

You can update a computer’s managed preference cache regularly. The computer

checks the server for updated preferences according to the schedule you set. The cache

is also updated automatically every time a change is made to any of the managed

preferences within Workgroup Manager. If you manage directory services using a

different tool, you can still use Workgroup Manager to update the cache at fixed

intervals.

To set an update interval for the managed preferences cache:

1 In Workgroup Manager, click Accounts.

2 Make sure the right directory is selected and that you are authenticated for it.

To switch directories, click the small globe above the accounts list. If you are not

authenticated, click the lock.

3 Click the Computer Lists button and select one or more computer lists.

4 Click Cache.

5 Type in a number representing how frequently you want to update the cache, then

choose an update interval (seconds, minutes, hours, days, or weeks) from the pop-up

menu. For example, you could update the cache every 5 days.

6 Click Save.

Note: Setting the cache interval to “0” turns off caching. Be aware that without caching,

managed preferences will not be in effect when the computer is disconnected from

the network.
