Notes WLCG AuthZ

Participants: Andrea, Andrii, Dave, Enrico, Jim, Julie, Linda, Mischa, Elvin, DaveK, Mihai, Roberta, Maarten, Jeffrey, Francesco, Brian, Mine, Petr, DavidC, Raul

Notes:

  • Pre-GDB summary
    • Policy
      • We seem to be missing docs on who makes authorization decisions etc. Maybe good to start with a risk assessment
      • Discussion needs to happen within IGTF as well (raised at TAGPMA)
      • IGTF has idea of self assessment, how would this process look for a token issuer? Who are the peers and what are the criteria?
      • US labs only allowed to do some things because DoE trusts IGTF processes
      • Note, we never accredited VOMS which is a bit more parallel to the token issuer
      • Possible actions
        • Add to workplan short document on how “it” all works, what is the token issuer and who authorizes what
        • Do a trial peer review of a self assessment of a token issuer (this would be a good test)
        • We should have a compliance test suite for the WLCG JWT profile (there is already something basic)
      • Which projects could we use to fund policy work?
        • Some existing projects e.g. EC ones
        • Should keep an eye out for good opportunities
    • ARC etc
      • Need to define the division of work
    • Dedicated meetings for token based workflows (or hackathon)
    • Rucio has a conflicting meeting on Thursday afternoons
  • “Token based bulk data transfer”
  • Also forward compatibility with mapping (not just backwards)
  • Try and spin up broader discussion with FIM4R and OIDF group and AEGIS r.e. next WLCG profile
    • Need to decide whether want to align with recent RFC
    • Moving towards a more general profile (possibly longer term)
      • Could use RFC as an excuse to get things going
    • Brian suggests starting email sending now before real work begins
    • What are we asking for from FIM4R etc? Find a way to make more broadly adoptable. Will merge WLCG and Sci-Tokens
  • FIM4R Signup https://fim4r.org/contact/
  • Petr: Could we have similar workflows for job submission as we have for download/upload? Yes, that’s next
  • CE scopes presentation from Brian

Actions:

  • Schedule next meeting (not Nov 25) for FTS & Rucio (include right people, Mihai, Petr)
  • Brian/Hannah to kick off activity for joint profile
  • Hannah update grid map activities in workplan to “Mapping”
  • Hannah clarify who will volunteer whilst on leave (until June 2022)
  • DaveD to help Hannah/CERN deploy htgettoken instance for testing
There are minutes attached to this event. Show them.
