[Samba] Change in smbpasswd in 3.0.6

[Christian Merrill]

Hi, we recently had a customer reporting that a script they run that 
includes an smbpasswd statement was no longer functioning after 
upgrading.  The smbpasswd command was being used to create an account 
and set a password -- taking the passwd as the second argument.  It 
looks like there has been a change in the code (possibly security 
related) and I was just curious what the offical reason is for it.

Line 177 samba-3.0.4/source/utils/smbpasswd.c
switch(argc)
has three case statements '0', '1', and '2'
in the case of '2', it takes the 2nd parameter and uses it as a password

Line 166 samba-3.0.6/source/utils/smbpasswd.c
switch(argc)
has two case statements '0' and '1'
for the value number of parameters that can be passed to the program

Thank you,
Christian
