samba - May 1999 - Password2

I'm so sorry, here my smb.conf file :
[global]
   workgroup = SES
   server string = Samba Server
   printcap name = /etc/printcap
   load printers = yes

   log file = /var/log/samba/log.%m
   max log size = 50

   security = share

   username map = /etc/smbusers

   socket options = TCP_NODELAY

   dns proxy = no

   lock directory = /var/lock

[homes]
   comment = Home Directories
   browseable = no
   writable = yes

 [printers]
   comment = All Printers
   path = /var/spool/samba
   browseable = no
   guest ok = yes
   writable = no
   printable = yes

[tmp]
   comment = sharing file
   path = /tmp
   read only = no
   public = yes

[public]
   comment = Public sharing
   path = /home/public
   public = yes
   writable = yes
   printable = no
