Horde not working with my Kolab

[Gunnar Wrobel]

Hi Stéphane,

current Horde CVS still requires a mysql db as backend.

As you mention: The database is necessary for "DataTree". Since Horde
maps the Kolab Groupware folders to Shares and these Shares are
managed within the DataTree framework you assumption that a database
is not necessary is not quite correct :)

Correct.

Without knowing exactly how you configured Horde it is hard to comment
on the errors. 

I believe one can get Horde to work on OPenPKG (even without a
database), but what you definitely need to do is to apply the Share
driver patch:

http://bugs.horde.org/ticket/?id=4263

There will still be minor issues but the groupware functionality
should basically work. There will be no more patches necessary for
Horde and I hope that this one patch will also finally find its way
into Horde CVS. But it is larger and touches more areas so it might
still take a while.

If you need specific configuration information concerning Horde you
can take a look at the configuration templates I use on Gentoo:

http://projects.pardus.de/kolab/browser/ebuilds/www-apps/

Each of the packages in that directory hold a "files" subdirectory
that (among other files) provides templates for automatic Horde
configuration. On Gentoo these templates get installed into
/etc/kolab/templates directory and they configure Horde automatically.

This would be one example:

http://projects.pardus.de/kolab/browser/ebuilds/www-apps/horde-kolab/files/horde-kolab-conf-20061120.template

I originally intended to write some instructions on getting Horde to
work on OpenPKG with the necessary patches applied. But since I plan
to move Kolab towards the current Horde package (Kolab still uses a
very old fork) I decided that it makes more sense to write these
instructions once the process is finished.

But in principle the Kolab side does not matter too much and applying
this one patch to Horde should be sufficient.

If you have any questions, please feel free to ask. I'll try to answer
them and maybe this can be the basis for a small HowTo on the
wiki. Would be nice.

Did not test that in a while.

There might still be issues even with the new Share driver. But I'm
not certain.

On Gentoo I have several people using the complete Horde groupware
functionality successfully with Kolab. I do still get bug reports and
there are still known open bugs (see http://bug.pardus.de) but the
basics are ok.

Cheers,

Gunnar
