JupyterHub Ldap Authentication Issue

JupyterHub
,
1

Hi,

I have an authentication problem when logging in. It gives an error as wrong username or password in the interface. When I look at the Jupyterhub log, I see the error No entry found for user ‘furkan.gayir’ when looking up attribute ‘sAMAccountName’. I share the configuration below. I would appreciate if you can support.

c.JupyterHub.authenticator_class = ‘ldapauthenticator.LDAPAuthenticator’
c.LDAPAuthenticator.server_address = “ldapserver”
c.LDAPAuthenticator.server_port = 389
c.LDAPAuthenticator.allowed_groups = [“ldapgroup”]
c.LDAPAuthenticator.lookup_dn = True
c.LDAPAuthenticator.lookup_dn_search_filter = ‘(&(objectClass=user)(sAMAccountName={username}))’
c.LDAPAuthenticator.lookup_dn_search_user = ‘ldapuser’
c.LDAPAuthenticator.lookup_dn_search_password = ‘ldappasswd’
c.LDAPAuthenticator.user_search_base = ‘ldapbase’
c.LDAPAuthenticator.user_attribute = ‘sAMAccountName’
c.LDAPAuthenticator.lookup_dn_user_dn_attribute = ‘cn’
c.LDAPAuthenticator.use_ssl = False

Thanks

Can you ensure you’re using the latest releases of LDAPAuthenticator and JupyterHub, turn on JupyterHub debug logging, and show us your full logs?

When I changed c.LDAPAuthenticator.lookup_dn_user_dn_attribute = ‘sAMAccountName’ and c.LDAPAuthenticator.lookup_dn_search_filter = ‘(sAMAccountName={login})’ i was able to overcome the problem I mentioned but a different error appeared. I installed the Ldapauthenticator package with conda without specifying any version. It automatically installed version 1.3.2.

Can you share your full JupyterHub config, turn on debug logging, and show us the full logs?

You are using LocalProcessSpawner which requires a local UNIX account on your JupyterHub server with the name furkan.gayir. Are you sure you have account exists on the JupyterHub server?

Yes, I tried creating this user on the jupyter server and the result is the same. Why is it asking for a local unix account when I can authenticate via ldap? What should I do to overcome this problem?

8

The authenticator only takes care of identifying the user. You’re using LocalProcessSpawner which also requires a JupyterHub user to have a corresponding local operating system user. One way is to ensure your operating system uses LDAP too, e.g. see
https://wiki.archlinux.org/title/LDAP_authentication#Client_setup
and there are plenty of other guides.

If you don’t want this you could look at DockerSpawner.

I solved the problem and logged in successfully. For reference, here are the parameters I added.
I added the following to jupyterhub_config.py:
def pre_spawn_hook(spawner):
username = spawner.user.name
try:
import pwd
pwd.getpwnam(username)
except KeyError
import subprocess
subprocess.check_call([“sudo”, “useradd”, “-ms”, “/bin/bash”, username])
c.Spawner.pre_spawn_hook = pre_spawn_hook
c.Spawner.cmd = [‘/data1/conda/bin/jupyterhub-singleuser’]
I changed the User in /etc/systemd/system/jupyter.service to root.

Thank you for everybody !
