Ical HowTo using Sunbird or Thunderbird/Lightning with working free/busy
Note: This is not an official Horde document. There is no write support in Horde 3.1/Kronolith 2.1
This document is intended to help administrators configure various parts of horde to link a calendar application with Kronolith. Please feel free to fill in any gaps or to clarify any existing information presented here.
Document Standards
In this document, we assume the following:
- The latest stable version of Horde and Kronolith.
- A working version of Horde and Kronolith.
- A working version of Sunbird or Thunderbird/Lightning extension.
On debian
- Install php pear package as follow:
<pre><code>
apt-get install php4-pear
</code></pre>
You can also use php5 package.
HTTP_WebDAV_Server
Then to make sure pear is working:
<pre><code>
pear config-show
</code></pre>
You now need to install the pear HTTP_WebDAV_Server package
<pre><code>
pear install HTTP_WebDAV_Server-beta
</code></pre>
- Adjust your apache config if necessary.<br />
We found that Sunbird was taking roughly 20 seconds to download the ics file over webdav and that even downloading the file in a browser had the same lag.  On investigation it turned out Kronolith was taking about 3 seconds to generate the file and Sunbird was waiting 15 seconds for the connection to close after downloading the file.  Turning off <a href="https://wiki.horde.org/KeepAlive">KeepAlive</a> in apache.conf (or setting it to a very small value) solved this issue.  The default is 15 seconds.
Test it
Launch your Sunbird or Lightning application.
- Go to calendar
- New ->
- On the Network -> iCalendar<br />
https://yourhost/yourhordepath/rpc.php/kronolith/YOUR-HORDE-USERNAME.ics
15/05/08: Starting with Horde Webmail 1.1 RC4, and as pointed out in <a href="http://thread.gmane.org/gmane.comp.horde.kronolith/4555">that thread</a>, this URL has to be changed like below:<br />
https://yourhost/yourhordepath/rpc.php/kronolith/YOUR-HORDE-USERNAME/YOUR-HORDE-USERNAME.ics
It should ask you for user and password.
Then you should see you calendar and be able to edit events in both Sunbird/Lightning and Kronolith.
I can read my calendar perfectly but not publish. My apache returns a 404 or 403.
Then it should work according to this:<br />
<a href="http://lists.horde.org/archives/kronolith/Week-of-Mon-20060130/005859.html">http://lists.horde.org/archives/kronolith/Week-of-Mon-20060130/005859.html</a>
Check also, whether the Apache config allows the PUT method. You should have something similar to
<pre><code>
        <Directory /home/www/cal>
          <LimitExcept GET POST OPTIONS PROPFIND PUT>
            Order deny,allow
            deny from all
          </LimitExcept>
        </Directory> 
</code></pre>
where /home/www/cal would be the directory under which horde is installed, in your Apache config.
Free/busy
Free/busy Lightning extension is able to correctly read Horde freebusy file.
Notes
- 26/03/08: With Lightning v0.7 and Horde Webmail 1.1RC3, reading and publishing works correctly with a remote calendar as described on this page.
- This does work very nicely with sunbird 0.7 and kronolith 2.2, you must select ical (not webdav) but you do get two way editing.
- 2011-11-23: Using SME Server 8b6, with smeserver-kronolith and kronolith-h3 installed (kronolith v2.3), and the pear additions from above, works fine with Thunderbird 8.0 and Lightning 1.0 -- paul dot warren at wollemisystems dot com

I have found the Solution!
this link has helped me <a href="http://lists.freebsd.org/pipermail/freebsd-ports-bugs/2011-July/214620.html">http://lists.freebsd.org/pipermail/freebsd-ports-bugs/2011-July/214620.html</a>
you have to install the pear-HTTP_WebDAV_Server
but it installed in the /usr/share/php dir
you must copy following files to your /usr/share/psa-pear folder, then you can write in your calendar form thunderbird or outlook
/HTTP/WebDAV/  to your psa-pear dir  (i think you must copy more than this dir) but it works
yourserer.com/rpc.php/kronolith/<yourid>/<yourid>.ics
Thunderbird ask you for a webdav authentification
Have fun
To get better Performance with more Than 20 Calendars, dturn <a href="https://wiki.horde.org/KeepAlive">KeepAlive</a> Off on your Apache server
so the loading on Mailclient should be much faster
