OAuth2 - Authentik
OliveTin has been tested with Authentik. This documentation page describes how to configure Authentik for use with OliveTin and assumes you already have Authentik installed and running.
Login as an Authentik administrator and start by creating a new app as follows;
Click Next, and on the Provider Type page select OAuth2.
Click Next, and on the Provider Configuration page, fill in the following fields;
Scroll down, and on the same page, copy the Client ID and Client Secret fields. You will need these to configure OliveTin.
Submit this wizard to save the configuration.
OliveTin configuration
The necessary OliveTin configuration is as follows;
authOAuth2RedirectURL: "http://localhost:1337/oauth/callback"
authOAuth2Providers:
authentik:
name: authentik
title: Authentik
clientID: "1234567890"
clientSecret: "123456789012345"
authURL: "http://localhost:9000/application/o/authorize/"
tokenURL: "http://localhost:9000/application/o/token/"
whoamiURL: "http://localhost:9000/application/o/userinfo/"
usernameField: "preferred_username"
icon: <iconify-icon icon="simple-icons:authentik"></iconify-icon>You will need to restart OliveTin for the changes to take effect.
Testing
You should now be able to login to OliveTin using Authentik, on the OliveTin page, a "Login" link should be available in the top right corner. This will take you to the login form, where you can select the Authentik provider.
Debugging
OliveTin logs OAuth2 flows quite extensively. If you are having trouble with OAuth2, you should check your OliveTin logs.
Next steps
Once you have OAuth2 working, you will probably want to configure access control lists in OliveTin. This is described in the Access Control Lists documentation page.
