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:



apt-get install php4-pear


You can also use php5 package.
HTTP_WebDAV_Server

Then to make sure pear is working:


pear config-show

You now need to install the pear HTTP_WebDAV_Server package


pear install HTTP_WebDAV_Server-beta


    Adjust your apache config if necessary.

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 KeepAlive 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

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 that thread, this URL has to be changed like below:
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:
http://lists.horde.org/archives/kronolith/Week-of-Mon-20060130/005859.html

Check also, whether the Apache config allows the PUT method. You should have something similar to


        <Directory /home/www/cal>
          <LimitExcept GET POST OPTIONS PROPFIND PUT>
            Order deny,allow
            deny from all
          </LimitExcept>
        </Directory> 

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 http://lists.freebsd.org/pipermail/freebsd-ports-bugs/2011-July/214620.html

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 KeepAlive Off on your Apache serverso the loading on Mailclient should be much faster
