To assist with controlling orphaned and dormant accounts, what can be used to indicate when an account is no longer active?

Account Expiration is used                              

Explanation:

Orphaned account is linked to an inactive employee. This means that even after an employee has left an organization, this account remains active.

A dormant account has not been accessed and had no activity for a lengthy period of time.

These type of accounts are a security vulnerability. For example an employee who has left the company in some unpleasant circumstances can steal confidential information using his account. To handle the dormant and orphaned accounts there should be a process that disables the account for employees who have left or dismissed and employee's access to the account should be ended right away. Moreover monitoring the accounts helps to restrain using other accounts. So the security risk can be reduced using account expiration. This involves the use of automatic expiration date for the user accounts or to set an account to expire once the its password is expired for a certain number of days. So the account will be automatically disabled when the contract period of the employee is ends.
