[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

# 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 #

# All NetBIOS names must be resolved to IP Addresses

# 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!

# on the local network segment
# - OR - are not deliberately to be known via lmhosts or via WINS.
