That was it!!! The /etc/ssh/sshd_config file is missing a few things. My
observation was in error that sometimes it worked for some users on a
misconfigured node.
So the next question I have is why doesn't that file always get updated
when ipa is configured? Is it supposed to be updated by ipa-client-install?
At least I know what to look for. I may just add this to my salt-stack
deployments so every node has the correct sshd config file.
Thanks!!

Can anyone suggest what else I can look at to troubleshoot what is going
on? Every user experiences this on different nodes.
Compare the sshd config files.
See if the authorized keys tool works:
/usr/bin/sss_ssh_authorizedkeys someuser
