The user calendar service is defined in a Class-of-Service definition called standardUserCalendar:
# # Definition for user calendar service bundle # dn: cn=standardUserCalendar,<ugldapbasedn> changetype: add objectclass: top objectclass: LDAPsubentry objectclass: extensibleObject objectclass: cosSuperDefinition objectclass: cosClassicDefinition cosTemplateDn: o=cosTemplates,<ugldapbasedn> cosSpecifier: inetCos cosAttribute: icsPreferredHost cosAttribute: icsDWPHost cosAttribute: icsFirstDay daServiceType: calendar user NOTE: When the Delegated Administrator configuration program installs the standardUserCalendar definition in the directory, the variable <ugldapbasedn>, shown above, is replaced by your root suffix (such as o=usergroup).
The daServiceType attribute defines this as a calendar service for users.
Note that the calendar service definition also includes calendar attributes such as icsPreferredHost.
However, Delegated Administrator does not provide service-package templates that specify values for these attributes. The Delegated Administrator console provides one service package with calendar service only: the standardUserCalendar service package. This package does not include calendar attributes.
