Question OpenBasedir: Can't include file from other domain

[TimoSchwiersch]

Hi,

I try to include a common directory, in which I's like to store a few classes that I use in multiple projects.
I added the location to the PHP-configuration:

{WEBSPACEROOT}{/}{:}{TMP}{/}{:}{/}var{/}www{/}vhosts{/}domain1.de{/}common.domain1.de{/}inc{/}classes{/}​

Then I tried to include one file:

<?php
require_once('/var/www/vhosts/domain1.de/common.domain1.de/inc/classes/input.cls.php');
$Input = new Input('test', 'select');​

But all i got was an error that the path "xyz" is not within the allowed path(s) "...:xyz"

It is EXACTLY the same path. So whats my fault? I'm confused...

Thanks for your help.
Timo.
