A few weeks ago I saw a Zeppelin ticket about multi-tenancy where users were able to use their underlying OS accounts. If I am not mistaken, users were even able to use different interpreters and notebooks. The related pull request had a small demo videos.
Unfortunately, I didn't bookmark the ticket and I don't seem to find it again. Provided I was not day-dreaming, could somebody kindly point me in the right direction? Thanks, Max.
