[Samba] smbpasswd with password on the command line

[Pedro Silva]

I've upgraded my samba server to 3.0.6 and without any warning the 
command smbpasswd no longer accepts passing the user password on the 
command line!

This was a very bad thing for me since the scripts I use to generate all 
my users account stopped working :-(

Anyone had the same problem? Any suggestions before rewriting everything....
