Authen to elastic with ldap config on which nodes?

Hi all
I have been testing for the feature to authen mine elastic server with ldap with one of my testing server, now i want to deploy it on the whole cluster, so which nodes do i have to config to get the feature working, master or data or all of them.

Thanks you for your time.
