Just for clarification: you can use Cyrus as a backend for address  
books and calendars in Horde, though not via CalDAV/CardDAV but via  
its generic IMAP backend (which has evolved from the Kolab backends).  
There is also a generic CalDAV backend support in Kronolith, but I  
haven't tested this with Cyrus' CalDAV server yet.
