To restore the default settings of all calendar LDAP attributes for a specific user, use the csuser utility reset command.
For example, to reset all calendar attributes of jsmith to the default configuration settings:
csuser reset jsmith
After a calendar user has been reset, all of the calendar attributes are removed from the user’s LDAP entry, including icsCalendarUser (object class), icsSubscribed, icsCalendarOwned, icsCalendar, and icsDWPHost (if in the LDAP CLD setup). A Calendar Server administrator will not be able to create calendars on the user’s behalf.
These attributes are restored in the user’s LDAP entry when:
The user logs back into Calendar Server, or
The Calendar Server administrator issues a csuser enable command for the user (although in this case, the icsDWPHost attribute is not restored).
