Any processes or jobs belonging to the deleted account must be removed:
Any objects owned by the account must be deleted or the ownership must be assigned to another user.
Any at or batch jobs scheduled on behalf of the user must be deleted. See the at(1) and crontab(1) man pages, if needed.
The user (account) name and UID must be retired and not reused.
