Yes it is.
You can publish the core certificates from different cores to the same CSA, so it shouldn't be a problem to have only one csa and multiple cores.
Yes, it is. You would just configure each core to point to the same CSA and make sure the core's certificates post to the CSA.
Wow, guess I got beat by a few seconds lol
Ok, I'll assume that the permissions (by Core) will be handled in/by the CSA response from server.
I have 2 cores with independent devices/independent permissions) The CSA just get the permissions from each core I assume.
Thanks for the fast response..
