    OAuth2:

    • from previous meeting Any news from issue WLCG and Token transition – reminders and requirements ?

      • Recently had a discussion with IaM developer (Andrea). Mostly technical.

    • We created a second certification setup where to test these OAuth interactions: CC7 box is there, as well as MySQL 8: started installing DIRAC there. The dteam IaM instance will be added there.

      • it was discussed if to add also the LHCb IaM but we decided against it
      • we should probably need admin access to dteam IaM – probably also managed by Andrea
        • Andrei+Andrii will ask about that

    • Andrii forwarded https://docs.google.com/document/d/1ZQzElD866yV6t9AomeW6r-L9s-64pNB95OFDd1EZEbA/edit?ts=60814a09#heading=h.ur0csvxkk8tc which contains technical drawings about the proposed implementation.

      • anyone can comment on it as now. Please do read it!

    • Andrii I will split the existing PR for making it easier to comment/understand

    tornado/HTTPs

    • NTR

    management

    • from previous meeting 1 task left for deploying on CVMFS
      • Not yet done
    • Add same check to VOMS_DIR and VOMSES as there is for CERT
      • Asked to add the created bashrc to qa branch of puppet modules
    • Q: Test on CentOS8? (for DIRACOS2/python3)
      • not really any need to do them (being conda-based it should be OK)

    COMDIRAC

    • NTR

    other externals, including Rucio

    • the Rucio client as of now requires a configuration file
      • changes there does not depend from us: issue has been opened and it’s being looked into.
    • PR: https://github.com/DIRACGrid/DIRAC/pull/5067
      • failing tests
      • no updates since last time
      • Cedric I would like to test the changes better that now. E.g. using github actions, or in a certification setup
        • Federico For the moment (this PR is for v7r0) just make it to pass the existing tests, and we can merge it. Once merged, the integration tests run by GitHub Actions can be added to release branch v7r2.
