Description:
------------
I have this vhost settings:

<Location />
  php_admin_value   open_basedir      /home/data/site.org/tmp/:/home/web/site.org/
  php_admin_value   doc_root          /home/web/site.org/
  php_admin_value   upload_tmp_dir    /home/data/site.org/tmp/
</Location>

doing a move_uploaded_file to the upload_tmp_dir result in a failure:

PHP Warning:  move_uploaded_file(): open_basedir restriction in effect. File(/home/data/site.org/tmp/FLOSG5_new.000) is not within the allowed path(s): (/home/data/site.org/tmp/:/home/web/site.org/) in /home/web/site.org/fileupload.php on line 11

In the same error string is visible that the upload_tmp_dir path is in the open_basedir directive.

I'm on a debian VM with linux 2.6.18 kernel, the /home dir is mounted via NFS and apache is chrooted with mod_chroot. 

Test script:
---------------
Any simple upload script with these lines of code:

[...]
    $from = $_FILES['uploadedfile']['tmp_name'];
    $flog = ini_get('upload_tmp_dir').$_FILES['uploadedfile']['name'];
    move_uploaded_file($from,$flog);
[...]
