[Samba] Access to a share resource without password

[J. L. Cabral]

Dear, I have a Linux Samba server and a Windows XP SP2 client joined
to the "g-company.net" domain.

I want to access a Linux share resource in /var/share without password
from WXP desktop FROM ANY USER.

This is my scenario:

- I don't create any Linux local user because I want total access from any user

- I use security = share

- My smbusers file is:

root = administrator admin
nobody = guest pcguest smbguest

- The Windows XP guest account is "guest" but I don't know if it has
any password setup.

- This is my smb.conf:

[global]
	workgroup = G-COMPANY.NET
	server string = Samba Server Version %v
	security = SHARE
	passdb backend = tdbsam

[share]
	comment = Archivos Compartidos
	path = /var/share
	read only = No
	create mask = 0700
	directory mask = 0700
	guest only = Yes
	guest ok = Yes

Form Windows XP I execute:

\\samba_server\share

but I get the error "DENIED ACCESS".

What can I do to access this resource ???

Thanks a lot,

JeLo
