Delegated Administrator (commadmin user create)(for Schema 2)
Calendar Server Utilities (csuser enable) (for Schema 1).
You can add enable both a new user and an existing user:
New user — When the user is created, using the New User wizard, assign the user a service package that includes calendar service. The user is automatically enabled.
Existing user — Select the user from the User List page and use the Assign Service Package wizard to select a service package with calendar service. The user is automatically enabled.
When creating a user, enable the user for calendar services, as illustrated in the example that follows:
commadmin user create jsmith -S cal
If you did not enable the user for calendar services when the user was created, you can add calendar services to the user later, using a modify command, as illustrated in the following example:
commadmin user modify jsmith -S cal
If you used csuser create when you created the user entry, the user is automatically enabled.
If a user sends a request to another user who has not been enabled for calendaring (that is, the user does not have a default calendar), Calendar Server returns the “Calendar not found” error to the user sending the request.
