So, I'm trying now with a clean install without using the SSSD Provider.  But, it is still an ipa client so sssd was running.  Do I still need jna and libunix installed if I'm not using SSSD?

You only need JNA and libunix if you would like to enable SSSD
Federation provider, other than that, ignore it.

I can be wrong. But looking at the description of your issue, it seems
like more related with SAML2 setup, than SSSD federation provider setup.
