  1. Refactoring/renaming components for V5 (Slack thread)

    1. Long discussion about how to reorg things, no decisions other than to revisit once we have a working Spring 6 build of everything.

    2. Scott will take an AI to write up a summary inventory of components in the various places right now














  • Success! https://shibboleth.atlassian.net/browse/JPAR-207

    • They fixed it. We either move to 3.3.2 or 3.4.0. The latter breaks backward compatibility with reporting-api < 3.1.0 - not sure we care, so should use 3.4.0.

  • https://shibboleth.atlassian.net/browse/JCOMOIDC-41 Pushed the changes I was working on to the oidc-common dev branch to support JWT signature validation using the new trust engine.

    • Works for resolving and validating the RSA signature on the id_token that comes back from the OIDC certification simple client test.

    • Added several misc. classes. Added an OP metadata credential resolver to extract ‘trusted’ keys from the jwks_uri.

    • Will need a resolver to acquire the client_secret for MAC validation - which I almost already have in the RP for resolving the client_authentication.

    • Maybe a resolver for PKIX style validation of the public key used using the x5c headers.





  • Testbed / Jetty 10

  • https://shibboleth.atlassian.net/browse/JOIDC-7

    • Bum-rushed adding JWT support to the remaining grants (not sure about refresh but I think that’s handled) in parallel with the design we just shipped.

  • https://shibboleth.atlassian.net/browse/IDP-1945

    • Logback defaults to debug, so relocating classpath:/logback.xml did a bad thing

  • Started work on next-stage of POC for SP service in Java

    • Making slow progress standing something up that parallels the IdP (sp.home, properties, etc.)

    • Experimenting with Spring context design for this, wondering about implications of a ReloadableService containing other ReloadableServices and what happens to the refresh threads if the parent service reloads.

    • Once there’s a viable Spring container, will add the Spring integration gateway in and start working on message endpoint registration API for components to call


  • Testbed with Jetty 10

    • Would like integration tests to work with the 10 branch, rather than creating a test-specific branch, as I thought 10 is the example for deployers

    • Do we just need to change the jetty.sslContext.keyStorePath in the 10-testbed-eclipse branch instead of 10 for the testbed ?

    • Would like to default the testbed / integ tests/ doc to Jetty 10

  • https://shibboleth.atlassian.net/browse/JPAR-197 Schedule for V5 ?
