Starting single-user notebook with our custom ldap docker image

I’ve done this before. It requires this change to the LDAPAuthenticator. You can then configure JupyterHub to extract the required LDAP attributes (username, UID), and pass them to the singleuser server by setting appropriate environment variables. If you start the singleuser server as root it will switch to that UID, which means it should be able to write to NFS as that user. I’ve written up some brief instructions:

Note the example is a bit out of date, but the general idea still holds.
