Horde should be able to connect to the users kolabHomeServer instead of 
localhost. I'm not sure how Horde is preconfigured in native kolab 
installations, but it is able to do that in general.

One drawback in your constellation are shared folders, which are shared on one 
server only. A user on server A can't share stuff with a user on server B. 
This can be avoided with "cyrus murder", a kind of cluster-enhancement for 
cyrus. It is a bit tricky in setup and certainly will need patches against 
kolabd.

Mhm, what are your goals? Centralized user management (Kolab) or decentralized 
user management (indipendet samba sites)?

Samba in combination with OpenLADP can be configured to use a local LDAP 
replicate for read access (authentication etc.) but a central master instance 
for write access (i.e. password changes). And even in such a scenario each 
site can have it's own samba PDC -- but you need to make sure that clients 
and servers can "see" only one samba PDC in broadcasts or netbios requests.
