[global]
	workgroup = OSIATIS
	realm = OSIATIS
	server string = %h server
	interfaces = eth0
	obey pam restrictions = Yes
	passdb backend = tdbsam
	passwd program = /usr/bin/passwd %u
	passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessfully* .
	syslog = 0
	log file = /var/log/samba/log.%m

	valid users = %S, root
	force user = root
	read only = No
	create mask = 0700
