lost in debuging freebusy + kontact

[Liutauras Adomaitis]

HI,

I can't setup Kontact to display free/busy information.
In kontact free/busy I have:https://<server>/freebusy/%EMAIL%.ifb as
server name and my login creds below. However Kontact "fails to parse
information received from server"
Apache logs show:
ip - - [16/Sep/2011:16:29:53 +0300] "GET /freebusy/<EMAIL>.ifb HTTP/1.1" 500 -

If I do curl for the server F/B location I get exactly the same error,
however if I do curl with "-u username" I get:expected result and
apache logs show
ip - <my login> [16/Sep/2011:16:26:56 +0300] "GET
/freebusy/<EMAIL>.ifb HTTP/1.1" 200 416

It looks like Kontact doesn't know how to authenticate.
If I set server location to use non https, then apache redirects to
http://<server>/client location and of course it fails.

Looked to wiki about trouble shooting, but:
- regenerate fails after regenerating users for one domain (we have 3
TLD configured on our Kolab) )with error:

Successfully regenerated calendar "user/<user>/Calendar@<other TLD domain>"!
Fatal error: Call to a member function getMessage() on a non-object in
/mnt/kolab/lib/php/Horde/Kolab/FreeBusy/Report.php on line 48

Kolab 2.3.2
Kontact 4.6.1

Any ideas?

BTW - I have changed the default behavior so https://<server>/
redirects to /client instead of /admin.
