Ask for help for setup authentik LDAP provider in Jupyterhub.

[renpj]

Describe your question/ I'm newbie for authentik. I'm trying to use the LDAP provider within Jupyterhub authenticator. I add the following part in jupyterhub_config.py:

c.JupyterHub.authenticator_class = 'ldapauthenticator.LDAPAuthenticator'
c.LDAPAuthenticator.server_address = 'ldap://127.0.0.1'
c.LDAPAuthenticator.server_port = 9000
c.LDAPAuthenticator.use_ssl = False
c.LDAPAuthenticator.bind_dn_template = [
    "uid={username},ou=users,DC=ldap,DC=goauthentik,DC=io",
]

It raised the connection refused error:

    Traceback (most recent call last):
      File "/usr/local/lib/python3.10/dist-packages/tornado/web.py", line 1790, in _execute

Hey,

while I cannot help you with that issue, you may want to take a look into the generic oauth from the https://github.com/jupyterhub/oauthenticator repo. I tried LDAP for a while but did not get it to work, oauth was working in 15-20 minutes.
