[Freeipa-users] Help with sshd configuration - ChallengeResponseAuthentication

[puck at i29.net]

I've run into a problem when setting up IPA for ssh logins. I've found 
that I need to set ChallengeResponseAuthentication to "yes" in my 
sshd_config to allow users to change their expired passwords on login, 
otherwise the login process just hangs and eventually times out. 
However, when I set it to "yes" password-less logins between my servers 
no longer work. Once I'm logged in, if I run a "kinit (username)" then 
the password-less login works again so I assume that when 
ChallengeResponseAuthentication is on, sshd just doesn't set that 
correctly. Can anyone recommend an sshd configuration that would allow 
both the password-less logins and allow users to change their passwords 
at login when they are expired?
