[clug] Samba help

Greetings all,

Can someone help me a little with samba? I have a samba server
configured for a local network, which needs to serve a share for a
network of 100 or so Windows pcs.

Although there is an active directory server I don't want to use
authentication for this server, I want everyone to be able to connect as
a guest with read only permissions.

However, I want ONE particular user on the network to be able to write
to the share.

If I have the security options off or manually set to 'user' then this
person can connect and write to the share perfectly. However, all other
users are prompted with a username and password. Makes sense.

So I set security to 'share' which enables all users to connect without
a password, however now the user I want to be able to write to the share

My guess is that samba just forgets about auth and connects everyone as
guest (?) but I want this user to be authenticated and allowed to write
to the share.

So perhaps I want something like: first try to authenticate the user, if
not, then connect with guest. This way he should be authenticated and
the share gives him write access, but all others are not authenticated
and therefore connect as guest, for which the share denies write access.

I hope that makes sense.. can anyone tell me what I'm doing wrong?

Box is running Etch. I've been fiddling with the smb.conf but here it is
in its latest state:

   workgroup = mshome.local
   server string = %h server
   dns proxy = no
   log file = /var/log/samba/log.%m
   max log size = 1000
   syslog = 0
   panic action = /usr/share/samba/panic-action %d
   security = share
   encrypt passwords = true
   passdb backend = tdbsam
   obey pam restrictions = yes
   guest account = nobody
   invalid users = root
   passwd program = /usr/bin/passwd %u
   socket options = TCP_NODELAY

   comment = Graphics
   guest ok = yes
   browseable = yes
   path = /data/samba/graphics
   writable = no
   create mask = 0775
   directory mask = 0775
   write list = chrissmart
   force group = chrissmart
   public = yes

Muchas gracias!
