Can't set open_basedir

Hi ... I have several virtual servers running under apache 1.3.20 and php 4.0.6, they are all locatet under one tree: /virt-servers/{name} At the current config apache is running as user nobody. this user has read ability on the /virt_servers dir. Now a user can read access the whole path, he can also read other users files, which may include usernames/passwords. Now I tried to set the value open_basedir, so that scripts for a specific virtual server can only access files within this virt-server my virt-server directiv in httpd.conf looks like this <VirtualHost 1.2.3.4> ServerAdmin me@me.com DocumentRoot /home/me/web ServerName eggi.me.com ErrorLog /apachelogs/eggi/errorlog/eggi_error.log TransferLog "|rotatelogs /apachelogs/eggi/transferlog/eggi_transfer.log 30" php_value include_path "/home/me/web" php_value open_basedir "/home/me/web" </VirtualHost> the value include_path is set correctly, which I checked with phpinfo() .. but open_basedir doesn't seem to be set ... someone knows why? any hints? -- mfg Marc Eggenberger
