Authority header in Service-to-Service invocation(gRPC) not being set correct

[rabollin]

Authority header in the Service-Service invocation request is set to “{daprappId}.{namespace}.svc.cluster.local” . The ask is how to get :authority header to be the same as resolved DNS name. ex: “{daprappId}.dapr”

the authority header that is being updated when the message is posted by the dapr sidecar of processor app is handled by GO. [[meta]: authority issues · Issue #4717 · grpc/grpc-go (github.com)] (grpc/grpc-go#4717) - This is an open issue on how GO/GRPC handles authority header and the scope for improvement.

Removing kind/bug as this is not a bug.

You can set the header with the grpc.WithAuthority option: https://pkg.go.dev/google.golang.org/grpc#WithAuthority.
As this is not (and should not be) configurable in Dapr, you'd need to make these changes to daprd here:

dapr/pkg/grpc/grpc.go

opts := []grpc.DialOption{
