When using IPA for managing user authentication you can come across this issue of SSH dropping just after a password change. It can be resolved by changing options in /etc/ssh/sshd_config. You need to be ROOT to make this change and restart SSHD service to take effect.
Edit /etc/ssh/sshd_config and change PasswordAuthentication to “NO” and ChallengeResponseAuthentication to “YES”
# vi /etc/ssh/sshd_config
And then make sure you restart sshd service and logoff and log in back for the changes tio take effect.
# service sshd restart
That’s it all done and you are ready to roll.
