kolab.conf SMTP access policy DB settings

Hi,

On a new installed Kolab 3 on Debian Wheezy I see the following entry 
in /etc/kolab/kolab.conf

[kolab_smtp_access_policy]
cache_uri = mysql://user:pass@localhost/database
cache_retention = 86400
address_search_attrs = mail, alias

I think there is some configuration missing for the DB access. Do I 
have to do this by hand or should this be done by setup-kolab?

Cheers,
Tobias
