Well, I'm only concerned about SQL backend.

If the Force_Change flag is set, then when the user logs in (with a
supplied temporary password), then they will be given a splash screen
to force the password change.  They cannot access imp, turba,
kronolith, etc, until they've done so.

I think in the horde base module is not possible because there's no
guarantee that the system has the possibility to change the password
unless passwd is installed.

As per the other replies, the first thing I have to do is look at
actually moving to a real SQL backend :)  However, I would have
thought this could be implemented even using IMAP to authenticate (in
the passwd module).  If not using an auth-backend that lists users,
the admin should be able to type in the user that has to be forced to
change their password.  e.g.

User forgets their password or account is compromised
Admin/helpdesk reset password and notify the user of the temporary password.
Admin/helpdesk uses the console to set the Force_Change flag for that
email address/username
User logs into Horde with the temporary credentials.  Because of the
Force_Change flag user is unable to proceed to applications until the
password change (using the passwd modiule) is done.

At least that's how I see it working (although obviously it would be
more coherent to be using an SQL backend.
