Roundcube Login on fresh Kolab 3.2 install on CentOS 6.5

Tue Jun 3 09:06:45 CEST 2014

Hello,

i got a fresh CentOS 6.5 installation and installed Kolab 3.2 as discribed here:
https://kolab.org/blog/zharvek/2014/03/19/installing-kolab-3.2-centos
All went fine. I'm able to get to the Admin Interface and could create Users. But the Users can't login on the Roundcube interface. 
I checked with cyradm the login and it works. I also could login in the Admin Interface with a created user. ActiveSync did't work too but it seems to be the same Problem as the Roundcube interface. 
Here are the logs I found so far:
