- Basic DPoP access token use case more or less covered now with token and userinfo
  - If public key thumbprint is stored inside our token claims sets, DPoP access tokens are issued
    - thumbprint may be fetched in PAR or authorize -flows, or via DPoP proof
  - Profile configuration option to control requirements & claims validators
- TODO
  - nonce-management
  - refresh token binding (public clients)
  - introspection and revocation support
JCOMOIDC-115 - Getting issue details... STATUS
- Upgrade is needed for the DPoP metadata-flag support: https://bitbucket.org/connect2id/oauth-2.0-sdk-with-openid-connect-extensions/issues/467/support-for-dpop_bound_access_tokens-in
- Before upgrade, we need a solution for a problem described in: https://bitbucket.org/connect2id/oauth-2.0-sdk-with-openid-connect-extensions/issues/438/non-uri-resource-indicators

May need to miss meeting, I have some people coming to fix our drains…
MDA 0.10.0 released. Huzzah!
- Some downstream work to be done before I’m really finished.
- main is now 1.0.0-SNAPSHOT and there’s a maint-0.10 branch.
- I don’t see value at present in nightly and multi jobs on the maintenance branch, but will create them if needed.
New Spring Framework releases (including a new 6.2 milestone) available, will integrate those.
Next up after that: Git conversion of the Santuario repository

JWEBAUTHN-12 - Getting issue details... STATUS
- Add a guard to check a user who has already registered a webauthn credential can not bypass webauthn authentication when registering a new one (under certain MFA configurations that allow some kind of alternate authentication to be used to bootstrap credentials).
  - In other flows, this is covered by requesting the correct authentication method/class principal etc
  - Is hard to think of all the options for trying to bootstrap the initial key, but I’ve tried to improve the documentation around this.
JWEBAUTHN-11 - Getting issue details... STATUS
- Pull user.id, user.name, and user.displayName from the attribute context for use when registering a new credential
JWEBAUTHN-8 - Getting issue details... STATUS
- Added an admin flow for admins to manage other users credentials. Only supports searching and removal for now.
Finishing the docs
3rd Alpha released. Will get a beta out before the end of the month. Hopefully not long after that for a v1.

SP design and prototyping
Conceptual model is visable in https://git.shibboleth.net/view/?p=java-plugin-shibd.git;a=blob;f=sp-conf-impl/src/main/resources/net/shibboleth/idp/module/conf/sp/agents.xml;h=6f5f1171a2ca15130f8cd009a0eee2e7e678428d;hb=HEAD
- Agents have a unique ID and contain Applications.
  - Agents will be associated with some form of identity/credential to secure requests.
  - Applications have an ID that is unique within a given agent and expose a RelyingPartyConfigurationResolver to resolve the correct RPC and PC for a request.
- Every layer allows override of the agent’s entityID, client_id, etc. The protocol identity is thus maintained solely in shibd and is no longer a concern of the agent. The shibd deployer is the one that associates Applications with protocol settings and ensures metadata given to IdPs, if it’s needed, is correct.
- Pluggable rules control the virtual hosts associated with an agent/application, similar to what supporting unregistered OIDC clients might look like.
