Sun Java System Calendar Server 6 2005Q4 Administration Guide

Delegated Administrator Utility (commadmin user delete)

To prevent a user from accessing calendar services, remove the service from the user’s LDAP entry, as shown in the example that follows:

commadmin user delete jsmith -S cal

This disables the user for calendar without completely removing the LDAP entry. In addition, this command changes the user's icsStatus to inactive.
