Yes? Yes to the example?
Is that example exactly what you are trying to do?
I understand about you wanting two certs…
But I don’t understand when you try to explain it all in just one sentence:
In short - “I need diff certs: 1 for purpose A and 1 for purpose B as well as A’s cert should only work for A”
Regardless if A and B are similar certs (or not), Cert A will always only work for purpose A and only A.
You may be trying to describe some “overlap”, but I’m just not understanding.
Please try to show exactly what you want more clearly.
As I did in my example.
Include as much detail as possible.
