I'm debugging as well. seems like wallace is doing the wrong lookup 
using shared at example.org instead of resource-beamer-beamer1 at example.org 
Not sure exactly where the error is buried.

Well but the packing is copying config.ini.sample to 
/etc/kolab-freebusy/config.ini and then setup-kolab is overwriting parts 
of the configuration using the given defaults.
But it looks with the newest changes in setup-kolab and freebusy that 
the default configuration seems usable apart from the imaps:// 
certificate problem.

Well ... it's the configuration that is supplied in the default vanilla 
setup and the only option apart from --generateall that works in kolab 
<= 3.3 This database error only happens when all directory 
configurations have been searched and ended up with no result. In this 
case it seems that freebusy is trying to do another lookup run with an 
empty or non-given configuration ending with the given database driver

Yes that works and the packages have already been updated. It was a 
packaging error.

That's was the biggest problem. Without a proper configuration I could 
only take the sample configurations and made them run. And tbh. I 
personally prefer the imaps:// over the generateall method because the 
ldap+imap version is also accepting alias addresses while the generated 
version only matches the primary mail which doesn't always has to be the 
address people are used to use.

Ah you're speaking about "that" daemon :-)

# kolab-freebusyd --help | grep daemon
   -d, --daemon              Run daemon (todo)
Which is marked as "todo" an therefore I didn't even looked at it that 
the development has been finished. I guess a init rc file is missing. 
IMHO I would consider imaps:// access for kolab-freebusy webservice the 
way to go for Kolab 3.3 (as it is close to release) and the fbdaemon 
could become the prefered method for the next Kolab version (3.4?). This 
way there's enough time to actually test and prepare the daemon.
