[horde] How to delete expired users

[Philipp Fäustlin]

Hello

I use Horde Groupware Webmail Edition 5.0.2 (with turba, kronolith, 
mnemo, nag). For authentication I have an imap server backend.

My problem now is how can I delete expired users from the Horde database 
completely?

In the admin section under users, it only says "Listing users is disabled."

Is there any script?

Regards,
