Finally got user accounts using authentik. Now I just need to get group based permissions at some point.

SSO Using Authentik

Preparation

The following placeholders will be used:

authentik.company is the FQDN of authentik.
nodered.company is the FQDN of nodered.

Step 1

In authentik, create an OAuth2/OpenID Provider (under Resources/Providers) with these settings:

note

Only settings that have been modified from default have been listed.

Protocol Settings

Name: nodered
Signing Key: Select any available key

note

Take note of the Client ID and Client Secret, you'll need to give them to nodered in Step 3.

Step 2

In authentik, create an application (under Resources/Applications) which uses this provider. Optionally apply access restrictions to the application using policy bindings.
note

Only settings that have been modified from default have been listed.

Name: nodered
Slug: nodered-slug
Provider: nodered

Step 3

note

We are assuming node-red is installed under docker

Navigate to the node-red data volume data/node_modules/. Alternatively enter the docker container sudo docker exec -it nodered bash and cd /data/node_modules

Use npm to install passport-openidconnect npm install passport-openidconnect

Edit the node-red settings.js file /data/settings.js

adminAuth: {
type:"strategy",
strategy: {
        name: "openidconnect",
        label: 'Sign in with authentik',
        icon:"fa-cloud",
        strategy: require("passport-openidconnect").Strategy,
        options: {
                issuer: 'https://authentik.company/application/o/<application-slug>/',
                authorizationURL: 'https://authentik.company/application/o/authorize/',
                tokenURL: 'https://authentik.company/application/o/token/',
                userInfoURL: 'https://authentik.company/application/o/userinfo/',
                clientID: '<Client ID (Key): Step 2>',
                clientSecret: '<Client Secret: Step 2>',
                callbackURL: 'https://nodered.company/auth/strategy/callback/',
                scope: ['email', 'profile', 'openid'],
                proxy: true,
        verify: function(issuer, profile, done) {
                done(null, profile)
        }
      }
    },
    users: function(user) {
        return Promise.resolve({ username: user, permissions: "*" });
    }
},
