samba - Mar 2009 - Unable to write files from the same group

Hi,
I have one share and two users that belong to the same groups : group1,
group2

I should be able to write files in the same dir since the are user.group
owned.

dir1 = user1.group1
dir2 = user2.group1

Since user1 and user2 belong to the same groups and the mask is 770 user1
should be able to write in dir2.  But it is not working.


[Documents]
    available = yes
    browseable = yes
    path = /myshare
    public = yes
    guest only = no
    writable = yes
    only user = no
    force group = general
    create mask = 770
    force create mode = 0770
    directory mask = 0770
    force directory mode = 0770
