samba - Sep 2008 - Unable to Create a LocalGroup, NT_STATUS_ACCESS_DENIED

I'm getting following response below to the command 'net sam
createlocalgroup demo -d 3':

I can't seem to find any real solutions to this problem, although I have
seen other users with similar posts.  Here's the relevant sections from my
smb.conf file:

[global]
server string security = ads
workgroup = DOMAIN
realm = DOMAIN.COM
encrypt passwords = yes
os level = 1
local master = no
domain master = no
preferred master = no
dns proxy = no
allow trusted domains = no
restrict anonymous = 2
load printers = no
printing = bsd
printcap name = /dev/null
disable spoolss = yes
log level = 3
admin users = root, Administrator
socket options = TCP_NODELAY IPTOS_LOWDELAY

Here's the relevant stuff from winbind.conf

idmap domains = DOMAIN
idmap config DOMAIN: default = yes
idmap config DOMAIN: backend = rid
idmap config DOMAIN: range = 1000-20000

winbind use default domain = yes
winbind separator = +
winbind enum users = yes
winbind enum groups = yes
winbind nested groups = yes
template shell = /bin/bash
template homedir = /home/%U

I've also noticed this in my logs whenever smb and winbind are restarted:

I'm trying to setup nested groups.  I would like to have a local group on my
Linux box that contains the members of an AD group as some of its members.  I am
running CentOS 5.2 and have used 3.0.28 that comes with it, and have also tried
with 3.0.32 provided by SerNet both have produced the same errors.

Any help someone could provide would be much appreciated.
