AGENDA

1. Santuario / Jakarta move → looks like 2.1 may be sunsetting pretty quickly, trying to get confirmation on a date

2. OIDC / OAuth coordination

3. (RDW) M2 verification is now on for IdP nightly build. Still outstanding (before we discuss other attacks)

   1. Process for accepting new certs - we have such a case outstanding for net.minidev:json-smart:2.4.7

   2. A plan for what to do if we do discover a forgery.

• https://shibboleth.atlassian.net/browse/JPAR-178 updated this. Seems OK - at least for now.

• Working on RP:

  • Profile configuration hookup (OIDC.SSO for now)

  • Message Encoders. Proposed to borrow the ideas used in the SpringAwareMessageEncoderFactory but for OAuth ResponseModes and RP authn request. In https://shibboleth.atlassian.net/browse/JCOMOIDC-27

• Work on commons:

Scott

• SP 3.3

  • Would be nice to figure out if it’s “safe” to build these on an M1 Mac at some point.

  • Package signing was an issue, ended up tunnelling GPG up to the server after uploading

    • Maybe look at doing the signing from within the Docker images somehow? Probably pretty hard to pull off.

  • Already one minor bug in the deprecation logging, waiting for more bugs before I release a patch.

• Started reviewing code for OAuth client_credentials grant and JWT token work

  • General comment: there’s a ton of very complex machinery and token bloat built around the “avoid resolving some attributes on the backchannel” issue. We never even bothered to deal with this in SAML and it was never that big a concern that I’m aware of…was this a big enough concern to warrant all that effort and technical debt? Maybe moot I guess.
