Calendar Server supports LDAP groups, which are a named collection of users. The group membership can be static, or dynamically created. Groups can be nested. Groups have a groupid that is analogous to a uid for a user. Groups also have a mail address.
In addition, groups can have a default calendar with a group calid that should correspond to the groupid, with the addition of the domain, for instance firstname.lastname@example.org. Group calendars do not have user interface preferences stored in the preferences database. Instead, the LDAP entry contains an icsDefaultacl attribute that is used in group creation.
A group is defined in the LDAP entry as an instance of icsCalendarGroup. For information on the other attributes available for group calendars, see the Sun Java System Communications Services 6 2005Q4 Schema Reference.
Log in as an administrator with permission to change the configuration.
Change to the /etc/opt/SUNWics5/cal/config directory.
Save your old ics.conf file by copying and renaming it.
Edit one or more of the following ics.conf parameters shown in the following table:
Owner attribute to use for groups and resources. The default is "owner".
Secondary owners attribute for groups and resources. The default is "icsSecondaryowners".
The attribute used to store the unique group identifier. The default is "groupid".
The attribute used to store the default ACL given to each group calendar at autoprovisioning. The default is "icsDefaultacl".
The attribute used to specify whether doublebooking of group calendars is permitted. This is the attribute used when a default group calendar is auto-created. The default is "icsDoublebooking".
The attribute used to specify whether invitations to group calendars are automatically accepted. This is the attribute used when a default group calendar is auto-created. The default is "icsAutoaccept".
The attribute used to specify the time zone for an auto-created group calendar. The default is "icsTimezone".
The attribute used to specify which groups a user, group, or resource is a member of, for ACL evaluation. The default is "aclgroupaddr". (For groups, this would be for nested groups.)
Save the file as ics.conf.
Restart Calendar Server.
If you plan to have calendars for groups, you need to configure group calendars. See To Configure Group Calendars.
If you are using groups, you should set the following domain level preferences in the group LDAP entry:
icsAllowRights — Set bit 15 to indicate your domain-level preference for group calendar doublebooking.
icsExtendedDomainPrefs — Set the groupdefaultacl property to determine the default ACL for group calendars in the domain.
For information on how to configure Calendar Server domains for groups, see 11.1 Configuring Domain Preferences for Groups in Calendar Server Version 6.3.
