YES! excellent - you came across the same problem that i did with 
smbpasswd, namely that it can't distinguish betwee newly added blank 
users, and users that have had their smb password account disabled.

not very useful from a configuration point of view...

by the way, the mods that i made clash nicely with yours: i added a 
system whereby you could do:

smbpasswd -add user passowrd - only as root.
