List users with last autentication datetime

Hi everyone,
thank you for the great product that I can freely use.

I would need a list of users who have not authenticated for a certain period of time. I tried the command:

privacyidea-token-janitor find --last_auth 100d --action listuser

but the output format doesn’t fully suit my needs. I need last datetime of autentication and other attributes like UPN or email of the users for sending notification.

Then I tried adding the following event:

event: "auth"
handler: "CustomUserAttributes"
condition: "result_authentication=ACCEPT"
action:
    set_custom_user_attributes
        attrkey: last_used_token_datetime
        attrvalue: {now} or {date} {time}

but the attribute values were always static.

Is it possible to get a list of users (ldapresolver) with their last authentication time and other attributes directly from the database, for example via SQL?

Thank you.
T.
