[Gllug] Winbind and AD issues

Hello,
I've been working on integrating a Fedora Core 2 box into Active
Directory over the weekend.. it's a file server running Samba.
I seem to have partial success but it isn't really working how I want it
to and maybe some clever person here can see the problem.
I've joined it to the AD and I see the computer account in there..
Kerberos seems to work:
***************
[root at NYC1LINUX01 test]# kinit administrator
Password for administrator at EWNS.NET:
[root at NYC1LINUX01 test]# klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: administrator at EWNS.NET
Valid starting Expires Service principal
07/25/05 06:30:19 07/25/05 16:32:49 krbtgt/EWNS.NET at EWNS.NET
renew until 07/26/05 06:30:19
Kerberos 4 ticket cache: /tmp/tkt0
klist: You have no tickets cached
****************
I can see users in wbinfo
*****************
wbinfo -u
[snip]
EWNS+scott.forsyth
EWNS+laurence.hunnex
EWNS+kristina.dolman
[snip]
wbinfo -g
[snip]
EWNS+EIG-LON1-Vodafone
EWNS+EIG-PAR1-WLAN
EWNS+EIG-PAR1-TeamParis
[snip]
*******************
and getent shows me users and groups from the domain.
/etc/nsswitch.conf has winbind listed after files for passwd shadow and
group.
chowning files to users works in a fashion.
*******************
[root at NYC1LINUX01 test]# chown EWNS+chris.park foo
[root at NYC1LINUX01 test]# chgrp EWNS+EIG-NYC1-Admins foo
chgrp: invalid group name `EWNS+EIG-NYC1-Admins'
********************
but chgrp doesn't work... this is my major problem.
My other problem is having to prefix the domain name (EWNS) to the
usernames - I should be able to get around this with use default domain
= yes in smb.conf but if I do that it doesn't resolve user names at all.
nscd is disabled.
Any thoughts? my smb.conf is attached
Thanks

# 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 made any basic syntactic errors.

# the "loopback" interface. For more examples of the syntax see
# the smb.conf man page

# Browser Control Options:
# 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 should be reasonable
; os level = 33
# 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 = no
# 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 = no
# Enable this if you want Samba to be a domain logon server for
# Windows95 workstations.
# 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)

# run a specific logon batch file per username

# All NetBIOS names must be resolved to IP Addresses
# 'Name Resolve Order' allows the named resolution mechanism to be specified
# the default order is "host lmhosts wins bcast". "host" means use the unix
# system gethostbyname() function call that will use either /etc/hosts OR
# DNS or NIS depending on the settings of /etc/host.config, /etc/nsswitch.conf
# and the /etc/resolv.conf file. "host" therefore is system configuration
# dependant. This parameter is most often of use to prevent DNS lookups
# in order to resolve NetBIOS names to IP Addresses. Use with care!
# The example below excludes use of name resolution for machines that are NOT
# on the local network segment
# - OR - are not deliberately to be known via lmhosts or via WINS.

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable it's WINS Server

# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
wins server = 172.22.32.20
# 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. The built-in default for versions 1.9.17 is yes,
# this has been changed in version 1.9.18 to no.
