Getting SMB to work on CentOS 5

I followed these instructions for command line setup.

http://www.centos.org/docs/5/html/Deployment_Guide-en-US/s1-samba-configuring.html

Make the following changes to /etc/samba/smb.conf

workgroup = ADS
server string = Matt's Penguin box, Samba Server Version %v


[mullermw]
comment = mullermw's stuff
path = /local/mullermw
valid users = mullermw root
public = yes
writeable = yes
printable = no
create mask = 0765

Be sure to set up a password for the user.

%smbpasswd -a mullermw

I'd like to know if there's a way to use the machine password.

When connecting, prepend the username with the domain: ADS/mullermw
