Maybe I'm missing something, but there doesn't seem to be any Win32 
function to get a username from a uid other than NetUserEnum, but 
I really don't think people running 'passwd bob' are wanting to enum
all users. The code to do it wouldn't be that hard, but it wouldn't
work for those people with domains (unless they specify a domain like
for mkpasswd).

Maybe mkpasswd should cache the info somewhere other than just /etc/passwd 
for this purpose? Or use the GECOS field?
