3.2.3.5. Introspection endpoint authentication
Some OIDC providers require authentication to its introspection endpoint by using Basic authentication and with credentials that are different from the client_id and client_secret. If you have previously configured security authentication to support either the client_secret_basic or client_secret_post client authentication methods as described in the OIDC provider client authentication section, you might need to apply the additional configuration as follows.
If the tokens have to be introspected and the introspection endpoint-specific authentication mechanism is required, you can configure quarkus-oidc as follows:
quarkus.oidc.introspection-credentials.name=introspection-user-name
quarkus.oidc.introspection-credentials.secret=introspection-user-secret
