Description of problem:
The following share:

[data]
        path                            = /home/data
        guest ok                        = no
        browseable                      = no
        read only                       = yes
        write list                      = @datarw
        directory mask                  = 0750
        create mask                     = 0640
        force user                      = data
        force group                     = datausers

should be: 
  inaccessible for "the world"
  readable by any valid user
  writeable by members of "datarw"

all users accessing this share are members of the group "datausers", 
the read/write users are members of "datarw", too. all files and 
directories in the share have the same permissions like defined in 
directory/create mask:

-rw-r-----   1 data datausers    444807 Feb  2 00:05 somefile
drwxr-x---   2 data datausers       392 May 20 11:02 somedirectory

This setup behaved as expected for years starting with redhat 6.x 
(and the corresponding samba version)up to fedora core 1 with 
samba-3.0.2-7.FC1.

in 3.0.4 it seems, that "force user" and/or "write list" is ignored, 
as the share is not writeable anymore.

Downgrade to 3.0.2 "fixed" the problem.


Version-Release number of selected component (if applicable):
samba-3.0.4-1.FC1

How reproducible:
Always

Steps to Reproduce:
1. Install samba-3.0.2 with security=user and the described share
2. Try to write to the share -> works
3. Upgrade to samba-3.0.4 -> no write access
    

Actual Results:  no write access to the share

Expected Results:  being able to write to the shared folder
