|2||Rainer Hörbe||SDP-MD02||I do not understand the explanation for [SDP-MD02]. If PKI with path validation is being used, there would be no hindrance to roll out new keys, even if metadata and assertions use the same key. I have seen a IDPs that publish their own metadata and the well-know location using the same signing key as for assertions.|
I think you may be correct about that and that the text is written with a presumption of the verification approach, and if we didn't specify that (and I don't think we did), it's open to methods that wouldn't have the problem we were concerned about. I think it needs work. Good catch.
|4||Rainer Hörbe||SDP-SP23||I think that the division of IDP-discovery into disco-UI and preference persistence is a significant improvement over the current IDP-Discovery spec, fixing the issue that embedded discovery results are not shared across SPs. See the RA21-proposal: https://groups.niso.org/apps/group_public/download.php/21376/NISO_RP-27-2019_RA21_Identity_Discovery_and_Persistence-public_comment.pdf. Rumor has it that Leif implemented it in pyFF.|
The discovery spec that's referencing never addressed UI or persistence, it's an interop protocol only, to enable a discovery solution to be injected into the flow, whatever solution it might be.
