php_admin_flag[disable_functions] = exec,proc_show etc etc etc.. didnt work but gives config errors and php-fpm cant start,
php_admin_value[disable_function]
worked, strangely though even while phpinfo() shows that these functions are now enabed for the client they still they don't work!
I need to enable them inside php.ini
phpmaxupload and maxpostsize worked fine per client with this method , strange !
Thank you very much for the example , at least now i can define max_memory and max_upload per client

PS: Please have a look at kloxomr repos, "/centos.alt.ru/" is not working and yum dont work unless disabled...
