Overlays in Consumer and provider configuration

Hello all,

I have some questions regarding overlay configuration for consumer and provider server.

It is necessary to load the same overlay modules in a consumer configuration? Is it also necessary to configure the overlay like in the provider configuration ?

There are overlays that are needed only for the provider, e.g. syncprov. Others are only needed for the consumer like the chaining overlay.

But for other overlays it is not that clear:

Dynlist needs to be configured for both servers.

But what's about dds, ppolicy and refinit? Here maybe a provider configuration is enough.

Is there a simple best practise ?

Thanks in advance.

Regards

Uli
