You can create users in LDAP using the following tools:
For Schema version 1, create both the user and the calendar at the same time using the Calendar Server csuser utility.
For Schema version 2, use Delegated Administrator Console to create the user with the Create New User wizard. Then create the users default calendar using the Calendar Server Utility cscal. See Appendix D, Calendar Server Command-Line Utilities Reference.
For Schema version 2, use Delegated Administrator Utility, commadmin user create. Then use the Calendar Server Utility cscal.
For further instruction on adding users in this guide, see 14.1 Creating Calendar User LDAP Entries.
