Authentik

1. Access Authentik Admin Interface:

• Open the Authentik Admin Interface in your browser. Can be found at a URL such as: https://authentik.example.com/if/admin/#/administration/overview.

We will use https://authentik.example.com as an example URL. Replace this with the URL of your Authentik instance.

2. Create a new Application and Provider using the wizard:

• Click on the Applications tab in the left sidebar and click on Applications again.
• At the top of the page you should see a button that says Create with Wizard. Click on it.

Note: You can also create an application and provider manually just be sure to link them afterwards.

• You can name the application whatever you want. For this example, we will name it LibreChat and click next.
• Choose the OAuth2/OIDC provider and click next.
• Choose your authentication and authorization flows.
• Scroll down and take note of the Client ID and Client Secret. You will need these later.
• Under Advanced protocol settings change Subject mode to Based on the User's Email.
• Click Submit.
• Add the new application you created to an Outpost.

Note: You should also apply any policies for access control that you want to apply to LibreChat at this point.

3. Gather Information for .env:

• You will need the following information from Authentik:
  • Client ID
  • Client Secret
  • OpenID Configuration URL

  All of these can be found by clicking on the provider you just created.

3. Configure LibreChat:

• Open the .env file and add the following variables:

OPENID_ISSUER=https://authentik.example.com/application/o/librechat/.well-known/openid-configuration
OPENID_CLIENT_ID=[YourClientID]
OPENID_CLIENT_SECRET=[YourClientSecret]
OPENID_SESSION_SECRET=[JustGenerateARandomSessionSecret]
OPENID_CALLBACK_URL=/oauth/openid/callback
OPENID_SCOPE=openid profile email
# Optional customization below
OPENID_BUTTON_LABEL=Login with Authentik
OPENID_IMAGE_URL=https://cdn.jsdelivr.net/gh/selfhst/icons/png/authentik.png

Note: Make sure nothing is wrapped in quotes in your .env and you have allowed social login.

4. Check Configuration:

• Restart LibreChat to apply the changes.
• Open an Icognito window and navigate to your LibreChat instance.
• Underneath the form login there should be a new button that says Login with Authentik.
• You should be redirected to Authentik to login.
• After logging in you should be redirected back to LibreChat and be logged in.
  • If you are not redirected back to LibreChat, check Authentik logs for any errors.
