[Samba] Changing ownership of a file or folder from within windows?

Hi everyone,
I have a Redhat 8 server running samba 2.2.8a and have configured samba
to use winbind so that I can control access to the file shares using
user and group accounts that have been set up in our windows NT domain.
This all works fine on the shares I set up from within the smb.conf
file. Windows 2000 users can access the shares just by logging into our
domain. But what I would like to do is control user or group access to a
file or a folder that has been created underneath one of the initial
samba shares. For example: if I have a samba share called "temp" and I
then access this share from a windows 2000 PC and create a new folder
inside "temp" called "myfolder" can I then go to the properties of this
new folder, click on the security tab and then add or remove users or
groups from the NT domain that can have access to "myfolder". At the
moment if I try do this I can add users or groups from our domain and
specify what access each should have ie: read only or full control, but
when I click on the "OK" button to apply these changes I get an error
saying "Unable to save permission changes on myfolder. Access is denied"
. Is this type of permission change possible and if so what am I doing
wrong?
Just as an asside, I have set samba up as a windows print server in the
past using winbind and our NT domain accounts/groups for authentication
and have been able to control access to the shared printers through the
security tab no problems.
Cheers
Tom
Below is a copy of my smb.conf file:
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not many any basic syntactic errors.

## Basic Server Settings
##
# workgroup = NT-Domain-Name or Workgroup-Name, eg: REDHAT4
workgroup = DPIWE
# server string is the equivalent of the NT Description field
server string = sybil
# This option is important for security. It allows you to restrict
# connections to machines which are on your local network. The
# following example restricts access to two C class networks and
# the "loopback" interface. For more examples of the syntax see
# the smb.conf man page
; hosts allow = 192.168.1. 192.168.2.0./24
192.168.3.0/255.255.255.0 127.0.0.1
# Uncomment this if you want a guest account, you must add this
to /etc/passwd
# otherwise the user "nobody" is used
; guest account = pcguest
# this tells Samba to use a separate log file for each machine
# that connects
#log file = /usr/local/samba/var/log.%m
# How much information do you want to see in the logs?
# default is only to log critical messages
log level = 2
# Put a capping on the size of the log files (in Kb).
max log size = 50
# Security mode. Most people will want user level security. See
# security_level.txt for details.
security = domain
# Using the following line enables you to customise your
configuration
# on a per machine basis. The %m gets replaced with the netbios
name
# of the machine that is connecting.
# Note: Consider carefully the location in the configuration
file of
# this line. The included file is read at that point.
; include = /usr/local/samba/lib/smb.conf.%m
# Most people will find that this option gives better performance.
# See speed.txt and the manual pages for details
# You may want to add the following on a Linux system:
# SO_RCVBUF=8192 SO_SNDBUF=8192
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
# Configure Samba to use multiple interfaces
# If you have multiple network interfaces and want to limit
smbd will
# use, list the ones desired here. Otherwise smbd & nmbd will
bind to all
# active interfaces on the system. See the man page for details.
; interfaces = 192.168.12.2/24 192.168.13.2/24
# Should smbd report that it has MS-DFS Capabilities? Only
available
# if --with-msdfs was passed to ./configure
; host msdfs = yes
##
## Network Browsing
##
# set local master to no if you don't want Samba to become a master
# browser on your network. Otherwise the normal election rules
apply
local master = no
# OS Level determines the precedence of this server in master
browser
# elections. The default value (20) should be reasonable
; os level = 20
# Domain Master specifies Samba to be the Domain Master
Browser. This
# allows Samba to collate browse lists between subnets. Don't
use this
# if you already have a Windows NT domain controller doing this job
; domain master = yes
# Preferred Master causes Samba to force a local browser
election on startup
# and gives it a slightly higher chance of winning the election
; preferred master = yes
##
## WINS & Name Resolution
##
# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable
it's WINS Server
; wins support = yes
# WINS Server - Tells the NMBD components of Samba to be a WINS
Client
# Note: Samba can be either a WINS Server, or a WINS
Client, but NOT both
wins server = 147.109.11.238
# WINS Proxy - Tells Samba to answer name resolution queries on
# behalf of a non WINS capable client, for this to work there
must be
# at least one WINS Server on the network. The default is NO.
; wins proxy = yes
# DNS Proxy - tells Samba whether or not to try to resolve
NetBIOS names
# via DNS nslookups.
dns proxy = no
##
## Passwords & Authentication
##
# Use password server option only with security = server
# The argument list may include:
# password server = My_PDC_Name [My_BDC_Name] [My_Next_BDC_Name]
# or to auto-locate the domain controller/s
password server = *
; password server = <NT-Server-Name>
# You may wish to use password encryption. Please read
# ENCRYPTION.txt, Win95.txt and WinNT.txt in the Samba
documentation.
# Do not enable this option unless you have read those documents
encrypt passwords = yes
# Should smbd obey the session and account lines in
/etc/pam.d/samba ?
# only available if --with-pam was used at compile time
; obey pam restrictions = yes
# When using encrypted passwords, Samba can synchronize the local
# UNIX password as well. You will also need the "passwd chat"
parameters
; unix password sync = yes
# how should smbd talk to the local system when changing a UNIX
# password? See smb.conf(5) for details
; passwd chat = <custom chat string>
# This is only available if you compiled Samba to include
--with-pam
# Use PAM for changing the password
; pam password change = yes
##
## Domain Control
##
# Enable this if you want Samba act as a domain controller.
# make sure you have read the Samba-PDC-HOWTO included in the
documentation
# before enabling this parameter
; domain logons = yes
# if you enable domain logons then you may want a per-machine or
# per user logon script
# run a specific logon batch file per workstation (machine)
; logon script = %m.bat
# run a specific logon batch file per username
; logon script = %U.bat
# Where to store roving profiles (only for Win95 and WinNT)
# %L substitutes for this servers netbios name, %U is
username
# You must uncomment the [Profiles] share below
; logon path = \\%L\Profiles\%U
# UNC path specifying the network location of the user's home
directory
# only used when acting as a DC for WinNT/2k/XP. Ignored by
Win9x clients
; logon home = \\%L\%U
# What drive should the "logon home" be mounted at upon login ?
# only used when acting as a DC for WinNT/2k/XP. Ignored by
Win9x clients
; logon drive = H:
##
## Printing
##
# If you want to automatically load your printer list rather
# than setting them up individually then you'll need this
; load printers = yes
# you may wish to override the location of the printcap file
; printcap name = /etc/printcap
# on SystemV system setting printcap name to lpstat should allow
# you to automatically obtain a printer list from the SystemV spool
# system
; printcap name = lpstat
# It should not be necessary to specify the print system type
unless
# it is non-standard. Currently supported print systems include:
# bsd, sysv, plp, lprng, aix, hpux, qnx
; printing = bsd
# Enable this to make Samba 2.2 behavior just like Samba 2.0
# not recommended nuless you are sure of what you are doing
; disable spoolss = yes
# list of users and groups which should be able to remotely manage
# printer drivers installed on the server
; printer admin = root, +ntadmin
##
## Winbind
##
# specify the uid range which can be used by winbindd
# to allocate uids for Windows users as necessary

# specify the uid range which can be used by winbindd
# to allocate uids for Windows users as necessary

# Specify a shell for all winbind user entries return by the
# libnss_winbind.so library.
