[Samba] Prevent smbpasswd lan manager field change

[Jansen Robert]

Added note:

The lanmanager smbpasswd filed change seems to happen also with some 
client machines do NOT explicitaly change their password. 
It rather seems that a client seems to enforce a zero LANMAN passwd if a client 
has a higher than LANMAN protocol available.

"I have a higher protocol than LANMAN, so forget the LANMAN method 
and scratch the unsafer password 
hash".

A wild guess,...


But the question remains, how to prevent this from happening ?

Running on a Solaris 9 

Ideas welcome.
