[users@httpd] Help with user/group

[HoWang Wong]

Hello,

I have just switch to 2.0 from 1.3, I found that I can't use user/group in vhost anymore. Is there any way to set it up?
Please help, because my server is hosting more than one site & I don't want the users can make use of Apache+CGI to read others files.

Thank you!
