Jupyterhub: PAM Authentication failed

Created on 19 Dec 2017 · 2Comments · Source: jupyterhub/jupyterhub

How to reproduce the issue
Install jupyterhub as shown here:
https://jupyterhub.readthedocs.io/en/latest/quickstart.html#prerequisites
start jupyterhub:
$jupyterhub
login with user running the jupyterhub instance
log out
log back in with another user on the system

What you expected to happen
I expect any user that has an account on the system to be able to log in to jupyterhub
What actually happens
I can log in with the user that is running the instance of jupyterhub
When trying to login with another user that I created via adduser from terminal
I get the following:
[W 2017-12-19 22:18:50.419 JupyterHub auth:563] PAM Authentication failed (test@::ffff:127.0.0.1): [PAM Error 7] Authentication failure [W 2017-12-19 22:18:50.419 JupyterHub base:351] Failed login for test [I 2017-12-19 22:18:50.447 JupyterHub log:122] 200 POST /hub/login?next= (@::ffff:127.0.0.1) 2543.74ms
Share what version of JupyterHub you are using
0.8.1
Running jupyter troubleshoot from the command line, if possible, and posting
its output would also be helpful.
