WLCG AuthZ Call


Attendees: Andrea, Maarten, Michel, Hannah, Romain 


  • We should start a mapping exercise with a  real storage interface to check that we have all scopes (try WebDav)
  • General advice from OIDF to keep token size below 2kb. For us we can keep them short but are dependent on how the VOs use the tokens.
  • Groups
    • Order of default groups is undefined
    • If you want fine control, should specify individual groups in an order
    • Default groups can be configured for the application (although there will be a baseline for all clients)

Note: pre-GDB Tuesday September 10th on Authorisation (possibly a followup meeting on the Thursday with wider community)


  • @Andrea to draft a table of WebDav methods to begin our scope mapping exercise (to have a look on the 6th of June)
  • @Hannah discover what the 2kb limits are, where the come from (e.g. HTTP Header length)
There are minutes attached to this event. Show them.
The agenda of this meeting is empty
