Hello @marrycheck! Just to confirm, did you add your admin user to the configuration (see the documentation) so that it will be authorized to login?

[ztcheck]

Thanks for your reply,@lambdaTotoro .I have added admin user to the configuration,and in the user_infotable,the value of is_authorized is 1.
I also did not see any errors except "Login failed".

Okay, I just set up JupyterHub with the current NativeAuthenticator on a fresh Ubuntu install and I couldn't reproduce this problem with a user called "admin", i.e. I can login just fine.

Could you make sure you start JupyterHub with the correct flags (jupyterhub -f /path/to/your/jupyterhub_config.py), the newest k8s-hub and making double sure you have the correct password?

In my env,i use helm to set up JupyterHub.Helm version is 0.9.1,and i have checked and tested the password several times,,,
I will change to helm version 0.10.2.
