Hi Daniel

Thanks a lot for reporting your findings! See some comments further below.

Known issue, we're working on that.

The message should be fully consumed by wallace and don't get passed
along. Need to investigate this.

These are just samples and are not supposed to be adapted by setup-kolab
for only serve as reference for manual configuration.

You likely have fbsource = imap://... configured which is not
recommended for productive systems.

However, the imap:// source uses the Roundcube framework to access event
data in IMAP and also attempts to use caching for this.

Symlinking /etc/roundcubemail/config.inc.php and
/etc/roundcubemail/defaults.inc.php in /etc/kolab-freebusy/ should
resolve these errors.

cacheto is optional and not required when free-busy data is generated by
kolab-freebusyd --generateall into /var/lib/kolab-freebusy/.

Some basic information is available here:
http://docs.kolab.org/architecture-and-design/kolab-freebusy.html

But full documentation of the configuration options is yet missing.

kolab-freebusyd now has a daemon mode which is the preferred way to run
it. It's intended to let the kolab-freebusy service connect to the
daemon and get updated free-busy data when requested:

[directory "kolab-ldap"]
...
fbsource = "fbdaemon://localhost:4455?user=%mail"

This is all bleeding-edge development and unfortunately isn't yet all
reflected in setup-kolab.

Same as above and should be solved with kolab-freebusy daemon.

True. The notes plugin has a "Create note" button in the top toolbar,
same as in calendars and tasks. But could be added in the list footer
for consistency reasons.
