[kronolith] Write in a remote calendar using WebDav

[serch]

Hi
I'm trying to use Kronolith to conect to a remote calendar, which is
provided by an http server using WebDav.
The problem is that I can't write in the remote calendar (I only can
open it in read-only mode).
I don't know if this is a limitation of Kronolith or if I have a
mistaken configuration.
I have this versions:
PHP: 5.1.6
Horde: 3.1.3
Kronolith: H3 (2.1.4)

Thanks a lot.
