Add items for discussion here



  • IDP-1657 - Getting issue details... STATUS
    • Fun with TLS!  We see different behavior when connecting to newer vs older target Linux systems with different versions of openssl.  Trying to confirm.



  • Polishing  JOIDC-5 - Getting issue details... STATUS
    • Testing client secret value resolution on test deployment
    • Polishing the configuration XMLs (also help documentation)
  • Premilinary studying  JOIDC-13 - Getting issue details... STATUS


  • Mostly complete:  GEN-264 - Getting issue details... STATUS
    • gitolite-config and personal repositories still unconverted. Probably declaring victory, assuming people don't think it's worth fixing gitolite-config (would require changes to Gitolite itself).
    • Meanwhile, I observe that the main branch in java-idp-jetty-base and java-idp-tomcat-base is surplus to requirements.
      • Proposal: remove the main branch in these two repositories and set HEAD to the most recent numbered branch (e.g., 9.4 for java-idp-jetty-base).
        ok with me --Tom
  • Progress on  JPAR-132 - Getting issue details... STATUS  (for  MDA-65 - Getting issue details... STATUS )
    • Have this working on one module (the important one) in java-metadata-aggregator. You can see it as part of the site for the product here:
    • Changes seem minimal:
      • Needs a build plugin instance and a reporting plugin instance.
      • Need to add test to the command line used to build the site, or it doesn't include it (probably fixable, if we care).
    • We could probably add these to the parent POM if we wanted this everywhere. I don't know if it would work everywhere, of course.
    • There's a Jenkins plugin to allow you to graph a summary from job results, perhaps the nightlies? Not using that yet.
    • Example output from mvn clean verify (with <haltOnFailure>false</haltOnFailure>):

  • Some leave, plus one more day tomorrow so will not be able to attend.
  • Closed  JDUO-10 - Getting issue details... STATUS  thanks to Scott's work on  IDP-1652 - Getting issue details... STATUS
  • Spent some time understanding where the supported principals were set, overridden, and used in order to (I think) add a strategy sensibly to the Duo validation action e.g.  JDUO-5 - Getting issue details... STATUS  (leaving open for now).
  • Updated to the latest Duo SDK ( JDUO-4 - Getting issue details... STATUS ). Adds more validation including id_token authentication.
  • Plugin POM now has the java-parent as the parent, works well. Updated to make explicit SL4FJ in the plugin.
  • Still, cleanups and tickets left.


  • Plugin management.  Installation now works (as does listing).
  • Update is all that left
  • Plus bugs
  • Plus tweaks:
    • UI work sucks.  The plugin interface will need extensive feedback.  Right now my approach is "The Perfect Is The Enemy Of The Good" 
  • Thinking about optional config files - I'd like to discuss briefly.


  • More support stuff than usual
  • JPAR-171 - Getting issue details... STATUS
  • IDP-1652 - Getting issue details... STATUS
  • IDP-1642 - Getting issue details... STATUS
  • Work all over the map on configuration, auto-wiring collections of configuration objects
  • Eliminated two existing files for the majority of deployers (some properties added or reworked to get at settings, so property file added)
  • Working on more property-driven settings for authentication flows
  • Will need to revamp more internals to autowire more objects like Principal serializers, Transcoder naming registry, all the lists that cause problems for plugins
  • Going from basic to advanced cases probably will need to rely on some way to document or produce XML snippets
