5. Error Codes
This page describes the errors that can occur during federation.
5.1. Authentication Errors
TODO for now, we only describe the errors here. Later, we should add exact error codes.
TODO we might want to merge one or more of these errors
authentication error: occurs when a backend queries another backend and provides either no client certificate, or a client certificate that the receiving backend cannot authenticate
: occurs when a sending backend authenticates successfully, but is not on the allow list of the receiving backend
discovery error: occurs when a sending backend authenticates successfully, but the SRV record published for the claimed domain of the sending backend doesn’t match the SAN of the sending backend’s client certificate
