Could it be that the DLL is somehow hardcoded and not found if pamela installed into the environment?

This is probably the key. pamela is a wrapper for PAM, which doesn't exist on Windows.

ArneBachmann commented 6 years ago

Yeah, that's what I gathered when I checked available conda builds for pamela, none of which were Windows targets. I found out how to disable pamela in the project jupyterhub (which is configured to use pamela authentication as the default, but doesn't install that dependency automatically).

Indeed! pamela was written for jupyterhub, which also doesn't officially support Windows, but it can be used on Windows if you use a custom Authenticator and Spawner.
