TLJH Signup and login customizations not working

[t3chbg]

Having few issues with login and signup custom pages not displaying after enabling Native Authentication - jupyterhub/nativeauthenticator#69 suggestions do not seem to work for me and having trouble figuring out what the issues are.

Ran pytest ad getting 2 error and 2 warning messages. Also not sure if these errors are related to the issue or not.

which version of NativeAuthenticator where you using? I just updated the package on pip, could you check if this problem persists?

Hi @leportella - I installed NativeAuthenticator as per instructions found here https://native-authenticator.readthedocs.io/en/latest/quickstart.html

git clone https://github.com/jupyterhub/nativeauthenticator.git
cd nativeauthenticator
pip install -e .

Git status output:
/opt/tljh/nativeauthenticator$ sudo git status
On branch master
Your branch is up to date with 'origin/master'.
nothing to commit, working tree clean

[leportella]

I see now that the error is because the authenticator can't find the original database:

'passwords.dbm' in ['passwords.dbm.dat', 'passwords.dbm.dir', 'jupyterhub.sqlite', 'passwords.dbm.bak'] or 'passwords.dbm.db' in ['passwords.dbm.dat', 'passwords.dbm.dir', 'jupyterhub.sqlite', 'passwords.dbm.bak']

Could you try with removing the importing users from FirstUse Auth option? If that works, please be sure to configure the correct database using the following confiugration:

c.Authenticator.firstuse_dbm_path = '/home/user/passwords.dbm'

as showed in documentation

[t3chbg]

@leportella no difference after removing the FirstUse Auth option.

If I recall accurately I added FirstUse Auth as troubleshooting step after experiencing issues. Just to confirm default folder path for passwords.dbm is /opt/tljh/state/passwords.dbm?

[t3chbg]

Current tljh config

users:
  admin: []
https:
  enabled: true
  tls:
    key: /etc/ssl/private/wildcard_ahri_org.key
    cert: /etc/ssl/certs/wildcard_ahri_org.crt
auth:
  type: nativeauthenticator.NativeAuthenticator
user_environment:
  default_app: jupyterlab
Authenticator:
  check_common_password: true
  minimim_password_length: 10
  allowed_failed_logins: 5
  ask_email_on_signup: true
  open_signup: true
limits:
  memory: 8G
  cpu: 1

[paulbaracch]

@leportella i have exactly the same problem in the same config.

[paulbaracch]

@t3chbg Did you find a fix to your problem?

[t3chbg]

@Paul-Barac not yet unfortunately.....

[consideRatio]

I noted this as well, but I haven't debugged this more in detail. Will try find time to do so in a few weeks, thanks for your effort to debug and document this experience so far! Note also that nativeauthenticator 1.0.5 has been released.

[consideRatio]

I think by using nativeauthenticator 1.0.5, and by configuring this in a jupyterhub config file:

import os
import nativeauthenticator

if not isinstance(c.JupyterHub.template_paths, list):
    c.JupyterHub.template_paths = []
c.JupyterHub.template_paths.append(
    f"{os.path.dirname(nativeauthenticator.__file__)}/templates/"
)

Things will work.
