Delay after invalid SSH logon?

UNIX Solaris

I am trying to configure a 4 second delay between failed login attempts on SSH.

You cannot with sshd_config, but with sshd2_config:

AuthInteractiveFailureTimeout
Specifies the server delay, in seconds, after a failed attempt to log
in using keyboard-interactive, password authentication. The default is
2.

And with a ssh-server-config.xml file:
<authentication-methods> <authentication action="allow"> <auth-keyboard-interactive max-tries="3" failure-delay="2"> <submethod-password /> </auth-keyboard-interactive> ... </authentication></authentication-methods>
