Hi @moscardo
The relevent PR for adding UID/GID support to the LDAPAuthenticator was merged but has not been released: https://github.com/jupyterhub/ldapauthenticator/pull/103
This where the LDAPauthenticator version is specified in Z2JH: https://github.com/jupyterhub/zero-to-jupyterhub-k8s/blob/9e1a7f98e55201c09ee52f3c6324cbd77228b0db/images/hub/requirements.txt#L25, it’ll need to be bumped after release.
If you need it now the best way is to follow this post which effetively embeds hte required LDAPAuthneticator changes in your JupyterHub config Starting single-user notebook with our custom ldap docker image instead of building a custom Docker image. It’s been a while but I’ll retest it if I get a chance.
If you can wait a bit I’ll see what’s needed to get it into Z2JH.
