Hi,
There's still an immense amount of work to do, but I'm happy to say that the SciTokens auth method was merged into HTCondor; you can use a SciToken to submit jobs to a schedd.
This is the first step (of many!) to start unraveling X509 usage from the grid community. Something to get excited about!
PS - Derek, what's the status of getting cvmfs-auth-helper released and into OSG?
