KeyError: 'getpwnam(): name not found: myname'

I’m not sure if this a jupyterhub or a ldapauthenticator issue.

I think I’m getting through the ldap configuration, but when i start a new notebook i get a 500 error.

I’m probably just missing a step, but not sure what it is.

Adding in jupyter_config.py

from subprocess import check_call


def pre_spawn_hook(spawner):
    username = spawner.user.name
    try:
        check_call(['useradd', '-ms', '/bin/bash', username])
    except Exception as e:
        print(f'{e}')
c.Spawner.pre_spawn_hook = pre_spawn_hook

helped for me

I am facing the same issue here. Did you manage find the root cause.
