first of all thank you for the hub, it has worked very well for us in teaching.
So far we have only a small test installation and now we want to go wide.
For this purpose, the hub is installed on an Ubuntu 20.04 on which PAM is configured on the system side. PAM works well system-wide and logging in via ssh works well.
Now I switched the hub to PAMAuthentificator, which also works but unfortunately not as expected: a new user with the prefix ‘jupyter-’ is created and only the credentials are fetched via PAM.
How do I get the hub to behave as if you were logging in locally via SSH, so it doesn’t create new users but simply takes the ones that are already there via PAM?
