In the main screen for Access Administration you can filter on status (Active and Deactivated) and it will provide you with those who had access and last login. I know this is not ideal or in a report form you can export the file (on the user screen) to filter the data on terminated sessions and last log in dates. You would need to make sure the check box for Hide Inactive Users is not selected.
The column headers that export with information are: Username, Email, Full Name, Account Status, Failed Login, Count, Last Login, Last Password Change, Last Failed Login, Created By, Updated By, Account Type
