how to get openssh 2.3.0p1 s/key to work

[dlm-ssh]

Haven't seen this mentioned here (probably because I've been too
heads-down trying to figure out why things weren't working), but
there's a bug in OpenSSH 2.3.0p1 such that S/Key authentication will
always fail when using protocol 1.  See patch below.

What I was really beating my head against was that, to have S/Key
authentication work when using protocol 2, you must enable both
SKeyAuthentication and KbdInteractiveAuthentication in sshd_config and
~/.ssh/config.  You'd think the former would imply the latter, but it
doesn't.  Also, there's no documentation on KbdInteractiveAuthentication,
as far as I can tell.
