Permission Help(deny others, allow group & Apache+Samba)

[Anthony Hawkes <ahawkes@debserv.boxzen.com>]

Okay need a bit of help,

I have a single folder call /folder in my root partition, basically I 
have created the group folder and added my user and every user that 
needs access, the perms on the dir are -rw-rw---, This works fine via 
Terminal or SSH however I also need the Samba daemon to give the same 
users the same permissions and I also need the apache2 daemon to have 
full access to the files in /folder, when the perms are changed and the 
group is added Samba rejects access over a network and apache scripts 
accessing the folder fail miserably.

I am not sure which users to add to group folder and what to modify to 
fix this problem up, I have googled my heart out and cannot figure this 
out can anyone give me some ideas
