When an account is deleted from the system, the System Administrator role and the Security Administrator role must take the following actions:
Delete the account's home directories in every zone.
Delete any processes or jobs that are owned by the deleted account:
Delete any objects that are owned by the account, or assign the ownership to another user.
Delete any at or batch jobs that are scheduled on behalf of the user. For details, see the at(1) and crontab(1) man pages.
Never reuse the user name or user ID.
