[conspire] ssh problem: disabling "keyboard-interactive"

[Peter Knaggs]

> UsePAM yes

I usually turn off PAM by setting it to "no". That way sshd only accepts
passphrase authentication (with the settings you've described).

I also set "PermitRootLogin without-password" which means password
authentication is disabled for root.

Try adding the second setting first, restart sshd, then try a root login.
Then add the second setting, and it should only allow passphrase for
all logins.

Peter.
