problems with suexec

[gobokster]

hi,
i'm following this howto on my Centos5.3 with ISPconfig3 ..
http://www.howtoforge.com/perfect-se...ispconfig-2-p7

all the installation working fine, but after i uploaded my site i have problem with my suexec because i always changing the group permission with apache when i'm trying to upload data via FTP and if via browser it always notice that i've wrong permissions.

[root@ns1]# /usr/sbin/suexec -V
-D AP_DOC_ROOT="/var/www"
-D AP_GID_MIN=100
-D AP_HTTPD_USER="apache"
-D AP_LOG_EXEC="/var/log/httpd/suexec.log"
-D AP_SAFE_PATH="/usr/local/bin:/usr/bin:/bin"
-D AP_UID_MIN=500
-D AP_USERDIR_SUFFIX="public_html"
[root@ns1#]

1) is there anyway that i can change it follow my vhost site user ?
2) if there no way to do it, is it safe to remove it and how?

thank you
