I am running OpenSSH 3.3 on OpenBSD 2.9 (using the 2.9 patch provided
for OpenSSH 3.3 on the 
OpenSSH web page).

The following lines of my sshd_config are different from the 
sshd_config
shipped with OpenSSH 3.3 (my config lines are listed here):
Protocol 
2
PasswordAuthentication no
ChallengeResponseAuthentication no
X11Forwarding 
yes

So I only allow protocol 2 public key authentication.

I can log in successfully with a 
public key, but the bug is that in
/var/log/authlog the entry says:
"Jun 26 09:44:46 zappa 
sshd[5986]: Accepted hostbased for nestler from 1.2.3.4 port 48831 ssh2"

It should say 
"publickey"; not "hostbased". It is definitely doing
a publickey login (according to "ssh -v -
v"), and not a hostbased
login.
