Actually I'm missing something like an `else' here. The authentication
on NT/2K/XP is done *instead* of making any authentication like calling
crypt() to verify the password or calling some PAM functions. You must
make sure that on NT/2K/XP that stuff doesn't get called. On 9x/Me
OTOH you still must use crypt() to verify the password. If you want to
see a really simple example, have a look into the login(1) source
