No lo había hecho y atendiendo a tus indicaciones lo he estado probando
entre otros comandos, haciendo un "smbpasswd -a -e -U nombre -w
contraseña" y sigo sin poder acceder al windows desde linux.
Ese usuario y contraseña solo me ha servido para solucionarlo de cara a
windows hacia linux (sin poder escribir en el home).
(al final pego el SAMBA.CONF por si nos puede dar alguna pista)

Lo monto con fstab.

Ya lo pude volver a dejar como antes, muchas gracias... desde cuando no
tocaba "unix" no había visto nunca el permiso "s" y por eso pensé que
era propio de esta distribución y no pensé que el man había cambiado
también en este aspecto,
muchas gracias no obstante.

#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which 
# are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash) 
# is a comment and is ignored. In this example we will use a #
# for commentary and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not many any basic syntactic 
# errors. 
#

#======================= Global Settings =======================

[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will
part of
   workgroup = MIRED

# server string is the equivalent of the NT Description field
   server string = %h (Samba, Ubuntu)

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS
Server
;   wins support = no

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT
both
;   wins server = w.x.y.z

# This will prevent nmbd to search for NetBIOS names through DNS.
   dns proxy = no

# What naming service and in what order should we use to resolve host
names
# to IP addresses
;   name resolve order = lmhosts host wins bcast

#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects
   log file = /var/log/samba/log.%m

# Put a capping on the size of the log files (in Kb).
   max log size = 1000

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
;   syslog only = no

# We want Samba to log a minimum amount of information to syslog.
Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to
log
# through syslog you should set the following parameter to something
higher.
   syslog = 0

# Do something sensible when Samba crashes: mail the admin a backtrace
   panic action = /usr/share/samba/panic-action %d

####### Authentication #######

# "security = user" is always a good idea. This will require a Unix
account
# in this server for every user accessing the server. See
# /usr/share/doc/samba-doc/htmldocs/ServerType.html in the samba-doc
# package for details.
;   security = user

# You may wish to use password encryption.  See the section on
# 'encrypt passwords' in the smb.conf(5) manpage before enabling.

# password database type you are using.  
   passdb backend = tdbsam guest

   obey pam restrictions = yes

;   guest account = nobody
   invalid users = root

# This boolean parameter controls whether Samba attempts to sync the
Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
;   unix password sync = no

# For Unix password sync to work on a Debian GNU/Linux system, the
following
# parameters must be set (thanks to Augustin Luton
<aluton en hybrigenics.fr> for
# sending the correct chat script for the passwd program in Debian
Potato).
   passwd program = /usr/bin/passwd %u
   passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX
\spassword:* %n\n .

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.
;   pam password change = no

########## Printing ##########

# If you want to automatically load your printer list rather
# than setting them up individually then you'll need this
;   load printers = yes

# lpr(ng) printing. You may wish to override the location of the
# printcap file

;   printcap name = /etc/printcap

# CUPS printing.  See also the cupsaddsmb(8) manpage in the
# cupsys-client package.

# also give this right to other users to add drivers and set printer
# properties

# on a per machine basis. The %m gets replaced with the netbios name
# of the machine that is connecting

package
