PHP Patch open_basedir for dynamic virtualhost

Hi all, it's a lot of time that i am trying to let Jason Greene open_basedir patch work with apache massive virtualhost. This is direct link to patch when it was developed: http://www.phpbuilder.com/lists/php-developer-list/2000101/0994.php This is a FreeBSD port more recent with same code: http://lists.freebsd.org/pipermail/freebsd-ports-bugs/2005-September/066983.html If i set to open_basedir directive (inside virtualhost config section) value VIRTUAL_DOCUMENT_ROOT, it works but i am not able to add static path like /tmp/ This is an example: VirtualDocumentRoot /var/www/php.net/%1 php_admin_value open_basedir VIRTUAL_DOCUMENT_ROOT user test.php.net is chrooted for php scripts in his homedir but he cannot write temporary files inside /tmp/ I tried with value %1; VIRTUAL_DOCUMENT_ROOT:/tmp/ and more but no way. These are my apps version: OS: Debian Sarge 3.1 Server version: Apache/2.0.54 (mpm-prefork pacchettizzata) PHP: 4.4.6 (Source) & 5.2.1 (Source) Any help will be useful and appreciated. Thank you all Regards
