Can't install Cartaro

Hi!

While installing Cartaro I get an error. After each try to install Cartaro, I get other errors. This is the last one. I don't know what I can do and what are my mistakes.

I use Debian, GeoServer 2.2.4, tomcat7, postgresql 9.1. The picture "Error" shows the error, after site configuration. My site configuration is shown in "Site config". For geoserver configuration I used http://cartaro.org/documentation/using-drupal-users-and-roles-geoserver documentation. I add a drupal authentication and user group service with exactly the same values and the same name to GeoServer. For all this I used the user root. Before, I configured geoserver/WEB-INF/web.xml and added geoserver-sec-drupal-7.x-1.0-beta5.jar to geoserver/WEB-INF/lib/.

I hope, you can help me.

Kind regards
Ines
