There are currently 3 known sources with instructions how to install Horde as the web client for Kolab:

# The [http://www.kolab.org/webclient.html official documentation], which hasn't been updated for a while.

## Some additional instructiosinstructions in the [http://wiki.kolab.org/index.php/Kolab2_Installation_-_Horde Kolab wiki].

# The folks at the Calgary Linux User's Group did a workshop on installing Horde and Kolab, and put together a good start. Their webpage is http://www.clug.ca/node/359, and I've taken the liberty of attaching their handout PDF to this page as well.
