I want to secure a rest service with basic authentication. The credentials should be used to obtain an access token from a keycloak instance for that client and check the allowed roles on the service.
The quarkus security architecture guide states that at least one extension installed that provides a username/password based IdentityProvider is required. It refers to JPA IdentityProvider and JDBC IdentityProvider, only. But I want to authenticate agains keycloak.
I have successfully setup a web app and a rest service with quarkus-oidc. It authenticates the user and provides access to the rest service via access token.
I also used properties files with basic authentication successfully.
My keycloak myclient setup has Direct Access Grants Enabled with Access Type set to confidential.
My configuration in application.properties:
quarkus.oidc.enabled=true
quarkus.oidc.auth-server-url=http://localhost:8180/auth/realms/myrealm
quarkus.oidc.client-id=myclient
quarkus.oidc.credentials.secret=secret
quarkus.http.auth.basic=true
Is this a valid combination?
When I debug into HttpAuthenticator constructor the only mechanism found is OidcAuthenticationMechanism, I'd expect BasicAuthenticationMechanism to be present.
