Ok, I found the answer myself:
the mechanism that set samba password same as linux password is pam!
Commenting lines with pam_smbpass.so from /etc/pam.d/common-auth and
/etc/pam.d/common-password solved my problem. Maybe Harmut problem to.

I have same situation. Samba 3.5 Ubuntu 11.10.
When user login in
their linux account (desktop environment, or via ssh, or whatever...)
samba password is reset to linux password. This is very annoying if
you wish to keep different passwords.
Can anybody tell me what mechanism set samba passwor
