[Samba] new to samba, pointers/guidance needed

[Ray Leventhal]

Hi all,

I've been fighting with samba for a day and a half and hope that I can 
get some guidance and/or pointers to info which I clearly need.

I'm running a small network, the Linux host (running samba) is CentOS 
5.1, fresh install.

The workstations are WinXP and the goal is to use the workgroup logins 
which people use on their local machines to access specific shares  on 
the CentOS box.  This network is wholly off-internet, so security here 
is not much of an issue.

I've a minimal smb.conf file installed (sanitized for your reading 
pleasure):

[global]
workgroup = <the workgroup name>
netbios name = <the netbios name of the CentOS box>
security = SHARE
passdb backend = <currently 'guest', but I think this is an issue>
[homes]
guest ok = yes
read only = no
[cpr tools]
comment = <description text>
path = /home/<some folder name>
guest only = No

and when I restart samba, this is the result in /var/log/messages 
(machine name is 'backup'):

I'd truly appreciate any pointers or outright 'do this' type stuff.

Thanks in advance,
