All Nodes are allways visible on both subdomains

Dear Developers,

We are very pleased with the possibilities, domain_access is promising. At the moment we are still having a hard time configuring it. Somehow all nodes are shown everywhere - but our node_access-table should not permit this. We know that users, which have administer nodes as a right can see all contents.

We started from a clean install regarding node_access - only one line. The current table is attached.

This is our webpage:

http://www.imb-uni-augsburg.de/

This is the subdomain:
http://lc-schule.imb-uni-augsburg.de/

We are only using one database with one set of tables - would like to have all content in the default tables and only control visiblitiy by domain_access_modul

In order to avoid errors from other parts, we have only activated domain_access and domain_content so far. Our options are:
Default domain settings
Primary domain name: www.imb-uni-augsburg.de
Name der Website: imb - Institut für Medien und Bildungsarbeit
Domain URL scheme: http://

Domain module behaviors
New content settings: Only show on selected sites
Content editing forms: Pass the default form values as hidden fields
Debugging status: Do not show debugging output
Sort domain lists: Creation order, oldest > newest

Advanced settings
Domain-based editing controls: Do not use access control for editors
Sucheinstellungen: Search content for the current domain only
Search engine optimization: Do not rewrite URLs
WWW prefix handling: Process all host requests normally

We really would appreciate any help or any advice.

Our intention is to have some small blogs, an ejournal and stuff hosted within one drupal-installation, sharing users and functions and so on.

regards
Christian
