        Tokens, HTCondor, Storage and our Facilities 30m

        We need to lay out the issues with the evolution of our infrastructure to tokens, replacing x.509. HTCondor 10.x will remove support for x.509 and our sites should already be capable of transitioning to this. However, storage still requires x.509 and the issues around replacing x.509 with tokens should be discussed.

        Brian and Ofer should summarize the issues and lead a discussion on these topics.
