SNI requests do not include port numbers, so all issuers with the same DNS hostname must use the same SNICertificateSecretName value even if they have different port numbers. 
+ SNICertificateSecretName is not required when you would like to use only the HTTP endpoints (e.g. when terminating TLS at an Ingress). It is also not required when you would like all requests to this OIDC Provider's HTTPS endpoints to use the default TLS certificate, which is configured elsewhere.
