I actually stopped using S/Key when ssh became prevalent, so I don't
have it set up any more.  However, the auth style stuff now works
for passwd and krb5.

The error message for approval is wrong, though.   auth_approval()
does not set errno, so it produces this sort of message:

djm at air 397 $ ssh catapult
djm at catapult's password:
Approval failure: Undefined error: 0
Connection to catapult closed.

It looks like you should be using error() instead of perror().
