ClientAuthenticationInterceptor (Connect2id Server SDK 4.44 API)

All Superinterfaces:

Lifecycle
```
public interface ClientAuthenticationInterceptor
extends Lifecycle
```
Service Provider Interface (SPI) for intercepting successful and failed client authentications at all Connect2id server endpoints where such authentication occurs, such as the token, token introspection, token revocation and pushed authorisation request (PAR) endpoints.
Successful client authentications can be subjected to additional checks and rejected with an InvalidClientException to produce an OAuth 2.0 invalid_client error.
Implementations must be thread-safe.
