IDM-03 Locking and withdrawal of user accounts in the event of inactivity or multiple failed logins
Automatically lock accounts of staff and automated system components left unused for two months, require authorised approval to reinstate them, revoke them outright after six months, and re-run the full granting procedure before any reissue.

The edition of the catalogue is not stamped here; check the edition your attestation is issued against.
These are the artefacts auditors commonly ask for on this requirement, our guidance rather than text from the standard. Your assessor decides what is sufficient in your context, and asks for samples across the period when a report covers one.

Common gaps auditors find
- Dormancy locking applies only to interactive staff logins and skips technical accounts
- Locked accounts survive far beyond six months because deletion is a manual housekeeping task
- Service desk reactivates dormant logins on a phone call with no recorded authorisation
