Jupyter Hub AD/LDAP Integration.

If you are in Enterprise environment, chances are you are already using Active Directory as standard authentication. Itegrating Jupyter Hub with you Enterprise Active Directory/SSO/LDAP will not only simplify user management in Jupyter Hub but is also very convenient for users. They no longer need to remember yet another username/password.

Also it is worth mentioning upfront that it is very easy and documentation is pretty good.

Pre-requisite

It is assumed that you have a working jupyter-hub setup with jupyterhub version >= 1.1.0 and python version >= 3.6

Set-up

First of all install jupyterhub-ldapauthenticator using:
pip install jupyterhub-ldapauthenticator
or
conda install -c conda-forge jupyterhub-ldapauthenticator

You will also need ldap3 module, which can be installed using pip install ldap3 or conda install ldap3. It is nice to see jupyterhub folks choosing to use ldap3, which is pure python ldap library.

Add following to jupyterhub_config.py in JUPYTERHUB_HOME.

	c.LDAPAuthenticator.lookup_dn = True
	c.LDAPAuthenticator.lookup_dn_search_filter = '({login_attr}={login})'
	c.LDAPAuthenticator.lookup_dn_search_user = 'ldap_search_user_technical_account'
	c.LDAPAuthenticator.lookup_dn_search_password = 'secret'
	c.LDAPAuthenticator.user_search_base = 'ou=people,dc=achowdhary,dc=com'
	c.LDAPAuthenticator.user_attribute = 'sAMAccountName'
	c.LDAPAuthenticator.lookup_dn_user_dn_attribute = 'cn'
	c.LDAPAuthenticator.escape_userdn = False
	c.LDAPAuthenticator.bind_dn_template = '{username}'

	c.Authenticator.admin_users = {'anuradha', 'admin'}
