Does this happen on a system with or without Volkers new fix?

Rowland I have not written the smbpasswd man page!

If the man page says the user must exist. OK, then i believe it is true. 
If the man page says this tool works against the local smbpasswd store 
then i believe it is true.
If the man page says the local passwd store is the file 
/etc/samba/smbpasswd then I believe it is true.

*And* if if read this document
https://wiki.samba.org/index.php/Samba_3.4_Features_added/changed
section *Configuration changes* i am pretty sure this thread waste a lot 
of time.
