That was it!

I'm guessing that the failover happened when I was upgrading the
machines, though jedgar was the first one upgraded and the other two a
few days later when things seemed to be working.  But I just added the
krb5_use_kdcinfo = false line to sssd.conf, restarted sssd, and the
'kinit' line succeeded.  Tried the web UI and it's working perfectly.
Will add that to the puppet config for IPA servers so the other two
should get it shortly and everything sorted.

Thank you very much for your time and assistance working through this.
