You can assign multiple service packages to a user or group.
When you assign a service package to a user or group, all the attributes and values in the service package are automatically assigned to the user or group.
To assign only calendar service to a user, use the standardUserCalendar service package. Calendar service does not have any associated attributes.
Assigning the standardUserCalendar service package is equivalent to using the -s cal option in the commadmin user create or commadmin user modify command.
For instructions on how to allocate and assign service packages, see the Delegated Administrator console online help.
