samba - Jan 2010 - PDC directory permission fail

Dear All ..
I use webmin to do the samba PDC configuration


The authentication is work well.

I've a problem with share permission, the condition is :
1. I've group named "warehouse"
2. I've user named "wh01", with home dir /home/wh01, and be a
group
member of "warehouse"

Both created via webmin.

3. Next I created share, named "warehouse"

[warehouse]
        comment = Files of warehouse
        writeable = yes
        path = /hdd2/samba/groupfiles/warehouse

when I create that share via webmin i use option :
a. mode : 775
b. Create user : Root
c. Create Group : warehouse.

4. From my XP station , I login to that domain with user name "wh01", 
the results is :
a. Successfull login
b. wh01 can create a file in the home directory (/home/wh01)

But, wh01 can not write file to share "warehouse"
why wh01 didn't have enough permission to "warehouse" while :

A. The share is created using group "warehouse", and
B. wh01 IS the group member of "warehouse", and
C. "warehouse" share is set to be available, and browseable.

Kindly please give me any enlightment to fix the problem

Sincerely

Which permission to the new file? May be 644? :)
IMHO, user have right to write directory, but have not right to write file.
Look man smb.conf for "force create mode", "force directory
mode" or
