According to this post Problem with OpenSSL netty_tcnative , for which I still did not find a solution after investing hours, I am questioning myself for what I need that.
What I want, as elasticsearch is only running on localhost and is not open to the world is just some form of authorization (user) against elasticsearch so the content cannot be read by everyone on the machine.
But it seems search-guard is not able to do this because TLS encrypted communication is mandatory for the install. Am I right with this assumption? Because tbh there is no need for a TLS communication if I communicate from localhost (graylog) to localhost (elastic) on the same node.
Are there any other solutions for this problem maybe.
Would appreciate any help, thanks!
