Hi.
in my pcd with the following config:
[global]
	workgroup = DOMAIN
	netbios name = brain
	server string = Controlador de dominio
	passdb backend = tdbsam
	os level = 35
	debug level = 10
	max log size = 50
	log file = /var/log/samba/%m.log
# PDC
	domain logons = Yes
	preferred master = yes
	domain master = Yes
	logon drive = H:
	logon home = \\%L\%u\.w9xprfl
# Usuarios y passwords
	smb passwd file = /etc/samba/smbpasswd
	encrypt passwords = yes
	username map = /etc/samba/smbusers
	unix password sync = Yes
	# Programas auxiliares y scripts
		passwd program = /usr/bin/passwd %u
		passwd chat = *New*UNIX*password* %n\n *ReType*new*UNIX*password* %n\n 
*passwd:*all*authentication*tokens*updated*successfully*
		add user script = /usr/sbin/useradd -m %u
		delete user script = /usr/sbin/userdel -r %u
		add group script = /usr/sbin/groupadd %g
		delete group script = /usr/sbin/groupdel %g
		add user to group script = /usr/sbin/usermod -G %g %u
		add machine script = /usr/sbin/useradd -s /bin/false \ -d /dev/null %u
# Note: The following specifies the default logon script.
	logon script = %G.bat
# This sets the default profile path. Set per user paths with pdbedit
	logon path = \\%L\profiles\mswprfl
# Impresi'on
	printcap name = cups
	cups options = raw
	printing = cups
	load printers = no
	printer admin = xavier,@root, root, @ntadmin, administrator
# Winbind
	idmap uid = 15000-20000
	idmap gid = 15000-20000
#	winbind separator = +
	#winbind enable local accounts = no
	#winbind trusted domains only = yes
        #template primary group = "Domain Users"
# Misc.
	#admin users = xavier,root, @root
	#security = user
	#getwd cache = yes
	socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
	nt status support = yes
	template shell = /bin/bash
	wins support = yes
	#template homedir = /home/winnt/%D/%U
... when I run the following cmds. in this server then a mssg. like this 
appear:
[root@brain samba]# net rpc join
Password:
Joined domain DOMAIN.
[root@brain samba]# net rpc testjoin
Join to 'IBCINC' is OK
but when I do:
[root@brain samba]# wbinfo -t
checking the trust secret via RPC calls failed
error code was  (0x0)
Could not check secret
WINBINDD is not running, should I run winbind in this server????
well, when I run winbind then:
[root@brain samba]# service winbind start
Iniciando servicios Winbind:                               [  OK  ]
[root@brain samba]# wbinfo -t
checking the trust secret via RPC calls succeeded
OK, but then I do:
[root@brain samba]# wbinfo -u
Error looking up domain users
Why?????
I need to use ntlm_auth in squid, do I need winbindd running in the server??? 
squid and samba (PDC) are running in the same server.
Thank you very much.
