secure users directory & custom php.ini (suPHP) for every domain

[nservices]

Hi,
i configure my server for custom php.ini (suPHP) for every domain
http://www.directadmin.com/forum/showthread.php?t=29387

the option apache_public_html=1 not work now (http://www.directadmin.com/features.php?id=497),
this mode set directory permission to 755 and group to username
instead of directory permission 711 and group apache

if i try to set group to apache, the php scripts not work for this directory (error 500)

how i can work with secure users directory & custom php.ini (suPHP) for every domain and secure users directory properly ?

Regards,
Nservices.
