Session authenticationv1.0+
Configure the OpenID Connect plugin to issue session cookies that can be used for further session authentication.
Here’s how session auth works:
sequenceDiagram
autonumber
participant client as Client <br>(e.g. mobile app)
participant kong as Gateway
participant httpbin as Upstream <br>(upstream service,<br> e.g. httpbin)
activate client
activate kong
client->>kong: Service with<br>session cookie
deactivate client
kong->>kong: load session cookie
kong->>kong: verify session
activate httpbin
kong->>httpbin: request with<br>access token
httpbin->>kong: response
deactivate httpbin
activate client
kong->>client: response
deactivate kong
deactivate clientFor a complete example of retrieving, storing, and using session cookies for authentication with Keycloak, see the tutorial for configuring OpenID Connect with session authentication.
Note: Setting
config.client_authtoclient_secret_postlets you test the connection to your IdP, but we recommend using a more secure auth method in production. You can use any of the supported client auth methods.
Prerequisites
- A configured identity provider (IdP)
Environment variables
-
ISSUER: The issuer authentication URL for your IdP. For example, if you’re using Keycloak as your IdP, the issuer URL looks like this:http://localhost:8080/realms/example-realm -
CLIENT_ID: The client ID that the plugin uses when it calls authenticated endpoints of the IdP. -
CLIENT_SECRET: The client secret needed to connect to your IdP. -
TOKEN_SALT: A random string that decK requires (v1.59 and later) so session credentials aren’t regenerated on every sync. This parameter is optional for other formats. For example, generate one withopenssl rand -base64 16.
