I transferred this issue from https://github.com/jupyterhub/the-littlest-jupyterhub.

@christineleroy are you sure you configured the LDAPAuthenticator correctly for TLJH? If so, this may be a bug in the LDAPAthenticator, otherwise its a support question related to TLJH configuration. Could you provide more details on how you configured TLJH to observe this? Then I can try to manually validate that part.
