Preliminary interoperability testing results of my Identity Provider [LINK] with other Relying Parties yield 5 Failures, 8 Working exchanges and 4 Not Applicables.
It’s a beautiful thing when the RP and IdP just "work". Checkout the results here [LINK].
For a semi-homegrown solution I’d say that’s not bad. Maybe instead of "trusting" someone with my valuable identity information, I can just be my OWN identity provider?
