I noticed in temporal cloud it’s possible to assign a CA Cert per namespace, but I don’t see it on the OSS version. Is there a way to assign a CA Cert per namespace?

Hi, yes my understanding is that this is a cloud specific feature which is based on OSS authorizer and claims mapper plugin concept (see docs [here](https://docs.temporal.io/security#default-jwt-claimmapper), example [here](https://github.com/temporalio/samples-server/tree/main/extensibility/authorizer)) so similar feature can be implemented by users (would need to be custom).
