yes, that's right. My kolab root is /usr/local/kolab. I think it  
should be like that everywhere cause it is documented  on the wiki page:
http://wiki.kolab.org/index.php/Kolab2_Installation_-_Source

What do you need to know? The system runs stable since 2005 apart  
from some errors in saslauthd.log saying not beeing able to bind to  
ldap (toltec client).
Another thing that never really worked was the freebusy but I never  
had those errors in apache-errors.log before. It's there since I  
updated to 2.1.

I checked if the user running apache (it is kolab-n) has sufficient  
permissions. He's got r+w:
-rw-------  1 kolab-n  kolab-n  7922  6 Jul 13:35 Kalender.imapcache
-rw-------  1 kolab-n  kolab-n   695  6 Jul 13:35 Kalender.pfb
-rw-------  1 kolab-n  kolab-n    83  6 Jul 13:35 Kalender.pfb.acl
-rw-------  1 kolab-n  kolab-n  1656  6 Jul 13:35 Kalender.xpfb
-rw-------  1 kolab-n  kolab-n    83  6 Jul 13:35 Kalender.xpfb.acl

Maybe it has something to do with the change described here (german  
Kalender):

Moreover, I am still not sure where to put the email domain kolab is  
responsible for (architekt-miro.de) and where to put the server's  
hostname (server.architekt-miro.lokal). That might be essential  
especially for FreeBusy generation. The bootstrap was years ago and  
maybe there is an error in the config since then?
For example, there is this parameter in fbview.conf.template which is  
not clear to me:
// What is the address of the Cyrus server where the calendar data is  
stored?
$params['server'] = '@@@fqdnhostname@@@';
It is $params['server'] = 'server.architekt-miro.lokal'; in my  
fbview.conf.

Thanks for your help
