PAMAuthenticator / LocalAuthenticator not checking primary group when using allowed_groups

woodmichl opened this issue · comments

Bug description

When trying to use PAMAuthenticator or LocalAuthenticator with the c.PAMAuthenticator.allowed_groups configuration parameter I wasn't able to log in even though users were in the set group and the correct password was entered. The error message in the logs was just a vague "User 'XY' not allowed.". Turns out the Authenticators seem to only check secondary groups.

How to reproduce

  1. Set c.PAMAuthenticator.allowed_groups = {"jupyter"} in jupyterhub_config.py
  2. Create user using useradd testuser -N -g jupyter
  3. Set password using passwd
  4. Start Jupyterhub
  5. Try to log in

Expected behaviour

The user should be able to log in because he has the correct credentials and is member of the allowed group.
In my opinion the primary group of the user should also be checked or at least there should be a note in the documentation of the allowed_groups configuration parameter.

Actual behaviour

The user isn't able to log in and the log message is very vague with [... JupyterHub auth:533] User 'testuser not allowed.

Welcome to the Jupyter community! 🎉

Thanks for reporting! This is definitely not the intended behavior, and we in fact had a recent related fix for spawner gids in #4628. The same change (os.getgrouplist instead of checking grp.gr_mem) should work for LocalAuthenticator, as well. Would you like to try a PR?
