Letting adult put the puppy in its place is good. If things ever get rough, and the adult dog is being bullied, I would step in and say "NO" to the puppy. And then separate them.
I'd also separate them and limit their interactions at first. For example, a few minutes each day, an hour each day, etc - but make sure you're watching them! As you observe they get along okay, then gradually increase their interactions. Friendships between puppies and existing dogs cannot be rushed. It takes time. They'll eventually get there.
