[Samba] File access rights and usernames from Windows XP client

[Achton N. Netherclift]

Hi,

I have recently set up a small network containing a Debian Samba 2.2.3a-12 
server
and Windows XP pro and Windows ME clients. The Linux box acts as a domain 
master,
and this seemingly works flawless with XP. However, I'm having trouble 
getting writeaccess
and translating the usernames on the XP client to the corresponding ones on 
the Linux box.

What I'd like to accomplish is this:

1) on share A, I'd like the XP client (geddeth) to gain full R/W access, 
using the share as root
2) on shares B-D, I'd like the XP client to gain full R/W access, using the 
share as <username>,
and group 'users'
3) on shares B-C, I'd like the ME client (anders) to have read access, 
using the share as <username2>,
and group 'users'
4) on share D, I'd like the ME client to have R/W access, using the share 
as <username2>,
and group 'users'
5) on shares B-D, I'd like everyone else to have read access only, using 
the guest account

So far, I've achieved some of the above. For instance, when browsing share 
A with the XP box,
smbstatus tells me the following:

Service      uid      gid      pid     machine
----------------------------------------------
a             root     root       294   geddeth  (10.0.0.4) Fri Jan 17 
01:15:57 2003

But I still only have read access. How can this be?

Using share B with the XP box returns the following:

Service      uid      gid      pid     machine
----------------------------------------------
b             root     users      294   geddeth  (10.0.0.4) Fri Jan 17 
01:16:11 2003

The groupid is correct, but the user is not. It should be translated into 
the machine name.
I also do not have write access to this share (goes for shares C+D as well).

Here's the smb.conf:

----------------------------------------------
[global]
   workgroup = WORKGROUP
	netbios name = ISILDUR
	server string = %h [Samba %v Linux]
	encrypt passwords = Yes
	map to guest = Bad User
	obey pam restrictions = Yes
	passwd program = /usr/bin/passwd %u
	passwd chat = *Enter\snew\sUNIX\spassword:* %n\n 
*Retype\snew\sUNIX\spassword:* %n\n .
	syslog = 0
	log file = /var/log/samba/log.%m
	max log size = 1000
	name resolve order = bcast host lmhosts
	printcap name = cups
  	domain logons = Yes
#  os level = 65
	preferred master = True
	domain master = True
	dns proxy = No
	guest account = guest
# wins support = Yes
	printer admin = geddeth
	hosts allow = 10.0.
	hosts deny = 10.0.0.1
	printing = cups
	username map = /etc/samba/user.map

[a]
	comment = Root
	path = /
	read list =
	write list = geddeth
	force user = root
	force group = root
	hosts allow = 10.0.0.4
	hosts deny =

[b]
	comment = a files
	path = /home/public/mp3
	read list = anders
	write list = geddeth
	force group = users

[d]
	comment = Incoming/downloaded files
	path = /home/public/incoming
	write list = anders, geddeth
	force group = users

[printers]
	path = /tmp
	printable = Yes
	browseable = No
----------------------------------------------

Any help is appreciated, thanks.
