If an exception is thrown by an implementation then the authentication attempt should be considered as failed and no subsequent GrpcAuthenticationReaders should be called. Additionally, the call will fail as Status.UNAUTHENTICATED. If the call instead returns null, then the call processing will proceed unauthenticated.

readAuthentication in interface GrpcAuthenticationReader

Parameters:

call - The call to get that send the request.

headers - The metadata/headers as sent by the client.

Returns:

The authentication object or null if no authentication is present.
