samba 3.2.5 commande root preexec client Xp

Hello,


I installed a version 3.2.5 via samba packages on a lenny. I have to 
manage different profiles depending on the user (teachers, students). So 
I use a section profiles in which I run the root preexec command  with a 
script that copy the correct profile depending on the user and group.

With Windows 2000 client - I have no problem -- preexec-command is 
executed only once at the beginning. But with the XP client  I have 
strange results.
The commande root preexec run at the beginning  - but when I 
disconnected - at the time of registration parameters I again run the 
preexec command.

I read many docs on the net but I do not know why I have multiple 
executions. I think I need to edit the registry key on the client XP - 
but I do not see that. If someone has already been confronted with this 
problem - any help would be welcome.

I create a test file is simple:
#! / bin / sh
echo "date" $ 1 "" $ 2 "machine" $ 3 "user" $ 4>> / var / log / samba / 
userlogon

and I get in userlogon --
   a line with the date and time, the machine and the user when entering 
the user
and a line with the date and time, the machine and the user when I leave 
the session
      
I put my smb.conf :
#
# 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
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483817 for a case
# where using a master file is not a good idea.

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

[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will 
part of
  workgroup = KILAUEA
  netbios name = himalaya
  netbios aliases = HIMALAYA

# server string is the equivalent of the NT Description field
  server string = %h server

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS 
Server
  wins support = yes


# 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
  hosts allow = 192.168.10. 127.0.0.1

  os level = 65

  domain master = yes
  local master = yes
  preferred master = yes

  time server = yes



#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
;   interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself.  However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
;   bind interfaces only = yes



#### Debugging/Accounting ####

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

# Cap the size of the individual log files (in KiB).
  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 = 1

# Do something sensible when Samba crashes: mail the admin a backtrace

####### 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/Samba3-HOWTO/ServerType.html
# in the samba-doc package for details.
  security = user

# 'encrypt passwords' in the smb.conf(5) manpage before enabling.

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using. #   passdb backend = tdbsam

log level=9

#   obey pam restrictions = yes

# 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 = yes

# For Unix password sync to work on a Debian GNU/Linux system, the 
following
# parameters must be set (thanks to Ian Kahan 
<<kahan at informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).
#   passwd program = /usr/bin/passwd %u
#   passwd chat = *Enter\snew\s*\spassword:* %n\n 
*Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

# 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'.

# (this is Samba's default)

# It specifies the location of a user's home directory (from the client
