Well I've eaten,
                       doing a bit of reading it would appear that mkpasswd only works wih NT varients ie
NT/2000/XP so with my 9x/ME it will always return a blank passwd and the -l option to mkpasswd will not
generate /etc/passwd entries for all users that have a windows profile but only the user running
configure.bat/mkpasswd. Cygwin passwd.exe <EM> may < /EM> be able to generate the password entry
after mkpasswd has created the /etc/passwd entries for the user. As we haven't got that (yet ???? Michele),
win 98/Me users are not going to be able to be able to log into sshd under cygwin.


login.bat <any user other than configure.bat user>

(if that makes sense) also fails due to the null passwd problem again because mkpasswd only generates one
entry in /etc/passwd rather than all user entries as -l option should give you.
