I've setup a new server, mostly following the Ubuntu 6.10 and ISPConfig guides. All works oke, but during the process of transferring websites to this new server, I'm puzzled by a permission problem between Perl and SuExec and hope someone has an idea. Although ISPConfig has added the right SuexecUserGroup, it appears that perl scripts do not use this user/group, but instead run with the euid and ruid of apache: www-data in my case. Any suggestion how to tackle this problem further? Details: Directory: Apache2.conf ... Error: The only other remark to make is that the perl routines/programs called by index.pl are stored outside the webroot. But the whole application works without a problem. If I change the ownership of the uploads directory (including the subdirs) to www-data, the nodes/files are created without any issue.
