[keycloak-user] OIDCFilterSessionStore

[Scott Rossillo]

For your first question, with OIDC there are three types of clients: confidential, public and bearer-only. For simplicity, let’s consider confidential, public as applications that you log into, for example, an e-commerce website. These applications have a session which stores the access token, ID token, and refresh token. When a request comes into the website the application, the session ID is used to establish who you are. This could mean making your OIDC tokens accessible to server side code.

A bearer-only application does not use sessions. It expects the OIDC access token to be sent in the authorization HTTP header on every request. It is a stateless application. Continuing your example, let’s say your e-commerce website needs to call a service that provides up to date inventory information when a user adds an item to cart. This can be a stateless service but wants to know what user is requesting inventory. The e-commerce website could retrieve the access token from the session and query the bearer-only application.

This is just one example, and a bit of an oversimplification of the things a confidential and public client can do. However, the point I’m trying to make is that by defining a client as bearer-only you are essentially saying it’s a stateless service that requires an OIDC access token on every request.
