Hi all! I'm working on Elasticsearch Cluster with 10 ES nodes for my client's project on production and already created cluster with 3 ES nodes on development . Nodes are like below: - Production 6 Hot (3 of them includes master role) 2 Warm 2 Cold - Development 2 Hot (includes master role) 1 Warm (includes master role) My client's about to test active directory configuration on development cluster first. Here's the question: - To apply active directory configuration, are all nodes need to be configured? - Or are there specific nodes that need to be configured? Thanks in advance! ---

_All nodes_ need to have the configuration applied. ---

Thanks for the reply. @warkolm Is it because all nodes have possibility to authenticate users? ---
