Horde (Kronolith and Turba) have there own ClaDAV / CardDav Server,
AFAIK Horde is at the moment not able to use cyrus as an Backend for
its calendars and address books.

Horde had support for Kolab, and the CalDAV / CardDAV in Cyrus is
based on what Kolab did there. But the support in Horde has not been
updated yet.

So most likely you have configured your thunderbird to synchronize
to horde and do not use the cyrus CalDAV / CardDAV feature
