Rob,
Thanks you are probably correct, unfortunately the CLI netted me a failure:
ipa config-show
ipa: ERROR: 2.44 client incompatible with 2.34 server at
u'https://ipa.foo.com/ipa/xml'

However, when run from RHEL systems it did indeed show what you expected.

I modified the default context to unconfined_u and after clearing the
sssd cache I logged back in as unconfined_u.

Thanks so much for the help in tracking that down,

-Erinn
