[Samba] Samba password synchronization

[eneko.astorkiza at ieuskadi.com]

Firstly excuse my english, i'm spanish.
 
I don´t know how to do this, maybe someone could help me.
 
I have a samba member server for a win2k3 domain. I have winbind
configured (it works fine).
 
Now i want to synchronize 2 users password.
 
Linux       ------------------    Win2k3 Domain
------------------------------------------------------------
 
root         ------------------     DOMAIN_Administrator
impresoras ---------------      DOMAIN_impresoras
 
How can i do this ???? it is posible using samba ???
 
What i want is from windows to linux, if i change the windows user
password, then the unix user password must change
 
Un saludo
