sshd PasswordAuthentication

[jack <lists@qnorth.net>]

Hi All,

Back in the woody days, I used to be able to set PasswordAuthentication 
to "no", and restart sshd which would only allow _keyed_ logins. But 
now, it doesn't seem to make any difference (users without keys can 
still login with normal pass auth without problems).

The sshd_config manpage doesn't seem to have any new warnings about 
PasswordAuthentication, and nothing caught my eye in /usr/share/doc/ssh..

How can I re-enable this wonderful feature! :)
Thanks...
