We're having trouble keeping track of who owns our Active Directory service accounts, especially when employees leave the company. Many accounts become orphaned, and we can't easily determine who created them, what systems use them, or whether they're still necessary. We currently manage this manually, which is time-consuming and creates security risks. What processes, tools, or ownership models have worked for you?

Avoid traditional service accounts when possible. Group Managed Service Accounts, and newer delegated managed service account options where supported, handle password rotation and reduce the ownership problem. The application or service should still have a documented business owner in the ITSM system, and retiring that service should include disabling its managed account.
Treat service identities like other identities in your IAM process. Require an intake request that describes the purpose, system, owner, technical contact, privileges, and credential storage location. Keep the account in a dedicated organizational unit, exclude it from employee lifecycle synchronization where appropriate, and require annual attestation that the access is still needed.
Use expiration and periodic review instead of letting accounts live forever. For example, require an owner to renew the account every six months or year. If nobody confirms the business need, disable it first, investigate any impact, and remove it after a defined retention period. Renewal notifications should go to both the owner and their manager so role changes don’t silently break the process.
Start by looking at authentication and audit logs to identify where an account is being used. PowerShell and directory reporting can show recent logons, while service and scheduled-task inventory can reveal which hosts depend on the credentials. If an account has no meaningful activity, treat it as potential technical debt and disable it carefully rather than assuming it is still required.
Make ownership part of the account’s required metadata. We put the responsible person or team in the AD manager field, record the purpose and a change-ticket reference in the description, and use a naming convention tied to the application or service. The account should also be linked to the corresponding service record in the CMDB or ITSM system.

This also helps with departures and transfers because the manager can nominate a new owner before the current owner leaves.
