[kronolith] error when executing reminders.php

[Wim]

Hi,
I have installed
Mysql 4.0.18
horde 3.0.4
Kronolith H3 (2.0.3)

I am using a SQL backend and I can store events without problems but
when i run reminders.php i get the following error in the horde.log

HORDE [error] [kronolith] Required 'password' not specified in VFS
configuration. [on line 73 of "/webroot/horde/lib/Horde/Scheduler.php"]
and
HORDE [error] [kronolith] Required 'password' not specified in VFS
configuration. [on line 109 of "/webroot/horde/lib/Horde/Scheduler.php"]

Where can I configure this?

Many thanks
