Ubuntu Multiserver Ispconfig Roundcube Setup Problem

I made two servers both running ISPConfig 3.0.5.1 and Ubuntu 12.04 LTS

Server One:
Web + FTP + DB + Webpanel

Server Two:
Mail + DNS

I want Roundcube to run on Server One and connecting to Server Two. I ran

Code:

apt-get install roundcube

and then:

Code:

dpgk-reconfigure roundcube-core

to set all the settings.

I used the standard config file for apache in conf.d and only changed the alias to webmail:

Code:

# Those aliases do not work properly with several hosts on your apache server
# Uncomment them to use it or adapt them to your configuration
#    Alias /roundcube/program/js/tiny_mce/ /usr/share/tinymce/www/
    Alias /webmail /var/lib/roundcube

# Access to tinymce files
<Directory "/usr/share/tinymce/www/">
      Options Indexes MultiViews FollowSymLinks
      AllowOverride None
      Order allow,deny
      allow from all
</Directory>

<Directory /var/lib/roundcube/>
  Options +FollowSymLinks
  # This is needed to parse /var/lib/roundcube/.htaccess. See its
  # content before setting AllowOverride to None.
  AllowOverride All
  order allow,deny
  allow from all
</Directory>

# Protecting basic directories:
<Directory /var/lib/roundcube/config>
        Options -FollowSymLinks
        AllowOverride None
</Directory>

<Directory /var/lib/roundcube/temp>
        Options -FollowSymLinks
        AllowOverride None
	Order allow,deny
	Deny from all
</Directory>

<Directory /var/lib/roundcube/logs>
        Options -FollowSymLinks
        AllowOverride None
	Order allow,deny
	Deny from all
</Directory>

This works straight away when I approach the server by http://servername/webmail, but not when I approach by approaching different sites setup by ISPConfig. The sites are setup with PHP-FPM. So I figured out that openbase settings might be restricting.

Therefore I changed the openbase settings in ISPConfig and added:
/var/lib/roundcube
/var/lib/roundcube/config
/etc/roundcube
/usr/share/roundcube

This resulted in some effect... I do not longer see a blank page, but now it complains that main.inc.php was not found. While this file is in /etc/roundcube and is configured. (Otherwise the direct approach wouldn't work, right?)

I see the following errors in the error.log:

Code:

I'm a bit lost right now... what could be wrong?

 

Ok.. sometimes solutions aren't that hard...

The problem was the permissions on the files in /etc/roundcube. All should be 644 and both debian.db.php and main.inc.php were for some reason different then the others (640).
