I have a question about setting Kerberos. I’ve seen a commit, where --with-gssapi flag was added. Since there is still no documentation about Kerberos(due to this issue being open), I have a question, which nodes should be set and added as principals for Kerberos? All nodes or only masters? As far as I understood, I can connect and execute queries on any node of the cluster, so each node should be added as a principal?
