I see entries like this when someone attempts to log into the machine (i.e. 
with telnet) but doesn't enter a username.  Off the top of my head, I can't 
remember whether I get this entry when I goof up an ssh login or not.  I just 
remember seeing it for telnet.  That might be easy to reproduce...  or maybe 
you remember goofing up a login that you can correlate to this entry?
