"Add Apache user to Unix group for new servers? - No" Option not saved!

I try to set this to "no" in the default template, click Save, yet my option isnt saved. User www is still added to user's group..
What file/line do i need to edit so i can manually tune this?

I dont need this feature as I use apache mpm-itk and all my user directories are created with 0750 perms.
On FreeBSD i've been experiencing a problem with apache being added to too many groups, after vmin adds it to (aprox) 14 groups it gives me this error:
[alert] (22)Invalid argument: initgroups: unable to set groups for User www and Group 80
and refuses to start. Havent yet managed to figure out how to solve this.
