[Samba] Force Create Mode & Unix Group Permissions

[Calvin Gordon]

[root at fedora1 common]# rpm -q samba
samba-3.0.2-7.FC1

I have a share called common

[common]
   comment = CrownAg Regina
   browseable = yes
   path = /home/common/
   valid users = +crownag-users
   writeable = yes
   force create mode = 0660
   force directory mode = 0770

common has several departmental subdirs
unix permissions on the subdirs are as follows:

drwxrwsr-x   7 cngordon crownag-users 4.0K Mar 27 10:23 bin_tracker_backups
drwxrws---   5 root     board         4.0K Mar 26 17:14 board
drwxrws---   7 root     design        4.0K Mar 27 16:00 design
drwxrws---  16 root     crownag-users 4.0K Apr  4 13:42 general
drwxrws---   3 root     mgmt          4.0K Apr  4 13:39 management
drwxrws---  13 root     marketing     4.0K Mar 30 08:25 marketing
drwxr-x---  16 root     crownag-users 4.0K Mar 31 10:58 users

Using windows on a remote machine, If I make a new sub-dir under any of the
department subdirs on the Fedora Samba Server, or copy a file from another 
machine to this share it is created with the correct permissions and group 
ownership.
If I move a directory and files from one dept sub-dir on the common share to
another dept sub-dir it ignores my unix group sticky and retains the original
group ownership.

This is behaving differently than other samba servers I have previously set 
up.  How do I force the moved files and sub-dirs to adopt the group ownership 
of the directory they are being mo0ved into?

testparm produces the following:

[root at fedora1 common]# testparm
Load smb config files from /etc/samba/smb.conf
