Summary
When using remote attestation, all clients must use the same SPID assigned to the service provider.
Description
Communication with a service provider is possible if two clients communicate using the same SPID, but authentication errors occur if each client uses a different SPID.
Resolution
In remote attestation, the service provider application gets one SPID. Each enclave that wants to attest and communicate with that service provider must use that service provider's SPID. An enclave cannot attest to a service provider with a different SPID.
