You can set the user preferences in the Preferences table in the administrative management utilities. Each user preference has a default value that is implemented until an alternative value is manually configured. In directory hierarchies, the preference values are inherited from higher level objects. However, the preference values set at the user object level override all higher level object values.
You can restrict users from setting or modifying the preferences.
Launch the Administrative Management utility (iManager, SLManager, or MMC snap-ins).
Click . The Preference properties table is displayed.
Locate the setting you want to change and then, in the Value column, select the appropriate value.
Some of the value settings are text field entries where you have to provide the value.
Click . The selected value is saved and the Administrative Management utility closes.
