There is a small environment, 4 ap will enough. I prefer to use ppsk local as authentication method, but it's a annoyingly to update user on each ap individually, so any possible to config one of AP as ppsk server, the others AP will query it when authentication. Then I could update user info only once.
By the way, ppsk local is my favor, not ppsk cloud.

When using PPSK local, unfortunately you will need to update each AP when adding a new user, there is no way to designate one AP to be a type of PPSK server for the others.
