OpenLDAP with LAM

!!! warning While this could stand on its own as a standalone recipe, it's a component of the sso-stack "uber-recipe", and is written in the expectation that the entire SSO stack is being deployed.

Ingredients

Docker swarm cluster with persistent shared storage
Traefik configured per design
DNS entry for the hostname you intend to use, pointed to your keepalived IP

Preparation

Setup data locations

We'll need several directories to bind-mount into our container, so create them in /var/data/openldap:

mkdir /var/data/openldap/openldap
mkdir /var/data/runtime/openldap/

Prepare environment

Create /var/data/openldap/openldap.env, and populate with the following variables, customized for your own domain struction. Take care with LDAP_DOMAIN, this is core to the rest of the sso-stack, and can't easily be changed later.

LDAP_DOMAIN=batcave.gotham
LDAP_ORGANISATION=BatCave Inc
LDAP_ADMIN_PASSWORD=supermansucks
LDAP_TLS=false

# Setup for github
OAUTH2_PROXY_CLIENT_ID=
OAUTH2_PROXY_CLIENT_SECRET=
OAUTH2_PROXY_COOKIE_SECRET=

Create authenticated-emails.txt, and populate with the email addresses (matched to GitHub user accounts, in my case) which you want to grant access, using OAuth2.

Create config.cfg

Setup Docker Swarm

Create a docker swarm config file in docker-compose syntax (v3), something like this:

!!! tip I share (with my patreon patrons) a private "premix" git repository, which includes necessary docker-compose and env files for all published recipes. This means that patrons can launch any recipe with just a git pull and a docker stack deploy 👍

Serving

Launch OpenLDAP stack

Launch the OpenLDAP stack by running docker stack deploy openldap -c <path -to-docker-compose.yml>

Log into your new instance at https://YOUR-FQDN. You'll hit the LDAP Account Manager login page, which will look like this:

Click on "LAM Configuration" to add a profile.

Enter a profile name, and a profile password (twice). Leave the template at "unix":

When prompted to save your new profile, enter the "master password" ("lam")

You've created a "profile". Now to configure your profile... Start with "Server Settings", and change your server address to ldap://openldap:389, and your tree suffix to the base DN you setup in the openldap.env file (above).

Under Security Settings, alter the list of valid users to "cn=admin<your-base-dn>"

After you save, you'll be redirected to the profile login page, where you'll need to enter the profile details and password you create above.

Once logged in, click on the "Account Types" tab...

And for both "Users" and "Groups", edit the "LDAP Suffix" to match your chosen Base DN, and save your changes:

After saving changes to your LAM profile, you'll be redirected to the LAM admin page. Enter your credentials (default admin/admin) to login. On first login, you'll be prompted to create the "ou=People" and "ou=Group" elements. Proceed to create these.

You've now setup your OpenLDAP directory structure, and hopefully won't have to interact with the "special" LDAP Account Manager interface much again!

Proceed to setting up KeyCloak...

Chef's Notes

What's not yet documented here is how to make the LAM "profile" configuration persistent. I.e., after each container reload, it's currently necessary to repeat the steps above.
