Version:            (using KDE 4.4.1)
OS:                Linux
Installed from:    Fedora RPMs

I'm running korganizer on a fully updated Fedora 12 system (kdepim-4.4.1-2.fc12.x86_64).  My department has been using WebCalendar to schedule some rooms and appointments for administrators and I'm considering trying to get them to shift to something I can synchronize better with korganizer, so these events show up on my personal calendar (which I don't want to store on the department server). We've got a test system running eGroupware (version 1.6.003-2, built from source since the Fedora rpms are not up-to-date).  

I tried adding the egroupware calendar as a groupdav calendar in
korganizer.  I used the url http://servername/egroupware/groupdav.php
(where servername is filled in correctly), with my egroupware username and
password.  When I click on "Update Folder List", I am offered something
that looks like 
   Folder                                  Events   Todos
    []    George Avrunin		      o
    []    Infolog [avrunin] Avrunin, George           o

(I clicked to make sure the circles on the right are filled in.)
So it looks like korganizer is communicating with the egroupware
installation.  I checked the boxes on the left, configured the cache to do
an automatic reload every 10 minutes and a save on every change, and clicked ok.  In the calendars list in the lower left in korganizer, I see a groupdav calendar checked.  

But events that I save to the groupdav calendar don't show up up in egroupware and events from the egroupware calendar don't show up in korganizer.  

After a response on the kdepim-users list from Ingo Klöcker, I found a posting from January 2009 that pointed me to the source of the problem.  It turns out that the entries in  ~/.kde/share/config/kresources_groupwarerc were of the form 
   http://servername/calendar/
So I changed all of them to 
   http://servername/egroupware/groupdav.php/calendar/
following the suggestion in the post from January 2009  I restarted korganizer, and events and to-dos from egroupware immediately showed up in korganizer.  An event I then entered in korganizer and saved to the groupdav calendar showed up in egroupware.

The bug seems to be that korganizer creates the wrong entries in the kresources_gruopwarerc file.  I don't know whether this is because egroupware reports something incorrectly or not.
