Kolab 3.1 on fresh Debian Wheezy

[Stefan Froehlich]

Since my Kolab 3.0 fails to upgrade to 3.1 properly on my old server I 
tried to install Kolab 3.1 on a fresh Debian Wheezy in a VM. For some 
reason I cannot get it to work. Installation went fine but when creating 
a new Kolab User in Webadmin it creates a user with no mailbox folders 
at all.
I remember I got it working once four days ago or so but cannot remember 
how I did this. After trying to replicate this installation on my 
physical machine it fails again.

Any special hints?
