There are currently 90,000 user accounts under my domain, and I have been manually deleting inactive accounts but it seems unproductive and a waste of time. I want to make use of provisioning API to delete these accounts, but I can't seem to find a way to retrieve the user accounts' last signed in date (to identify which are the inactive ones). Are there any methods which allows me to retrieve the last signed in dates of all user accounts? Thank you.
