Add items for discussion here



  • Looking at Scott's SAML proxy flow stuff.  Will probably have detailed questions soon.
    • Testbed
      • Jetty 9.3 vs 9.4 - prefer or recommend one or the other?
      • Eclipse requirements? The Jetty 9.4 wiki page mentions Eclipse 2019-06 - is this a hard requirement?


  • LDAPDataConnector updates for ldaptive


  • The OIDC plugin certification finally completed, see
  • Worked on the ways to configure RP's public keys into SAML metadata, currently three ways:
    • via RoleDescriptor/KeyDescriptor (using OpenSAML's InlineX509Provider and RSAKeyValueProvider)
    • via (custom) RoleDescriptor/JwkSet -element: contents expected to be base64-encoded JWK
    • via (custom) RoleDescriptor/JwkSetUri -element: URI to the endpoint where JWK can be fetched
  • Next release (v1.1.0) targeted before TechEx
    • The GÉANT BSD license will be switched into Apache 2.0




  • Finished testing all views when CSRF protection enabled - CSRF FlowExeuctionListener testing, all views overview
  • Cleaning up implementation Anti-CSRF FlowExecutionListener Implementation. Not quite my best effort yet, but pushing it to ( branch feature/anti-csrf-flowlistener) for review by an interested party.
    • Questions
      • Currently, if enabled, affects all views unless they are excluded. As this will be disabled by default, risk that changes that appear to work will break when enabled (which a deployer may have chosen to do). Is it best to use includes views over excludes.
        • Would need to ensure good integration tests for view. 
        • Not as tight security wise, but the IdP has a low risk of CSRF anyway...
      • I need to be clear which views are going to be included (although is in the big table above, probably needs better communication).
      • If deemed usable, how does this get fitted into the IdP e.g. requires changes to views in addition to system config.


  • IDP-1499 - Getting issue details... STATUS   (and related) Just needs testing
  • IDP-1516 - Getting issue details... STATUS
  • LDAP test failures in eclipse..  Status?


  • IDP-1511 - Getting issue details... STATUS
  • IDP-1494 - Getting issue details... STATUS
    • Work progressing on production of authentication result, implications on subject c14n, additions needed to support obvious use cases
      • Considering generic extension point to turn Assertions into arbitrary IdPAttribute data to include
    • Inbound filtering seems to hold up (issuer is proxied IdP, requester is proxying IdP)
    • Starting to hit the interesting questions, e.g. when did authentication take place re: lifetime for SSO in IdP
