Thats right, the NT-Client using encrypted password transfers no "old
password" to the PDC (samba), so samba couldn't use it for the

The passwd-programm is called by samba as root and normally there is no
need for the old password, because root could change the user-password
without it.

We habe already the same problem, because our UNIX-password are
NIS-Passwords and it is not possible - also as root - to change the
NIS-password without having the old password.

Somebody tells me about a hacked yppasswd, working without the old
passwords, but I can't find something similar like this in the web.

Do anyone know about a yppasswd changing passwords (as root) without
asking for the old password ?

Thank you
