We’re trying to set up Datahub with the contributed Helm charts and self-hosted elasticsearch. I’ve tried looking through the code, and cant find any reference to authentication for ES. The only thing I could find was in this file where we set

xpack.security.enabled=false

which to my understanding disables authentication all together. Is it really the case that there is no support for authentication towards ES?

Internally we use our proprietary authentication method, and that's probably why it's disabled by default in OSS. Orthogonally there's a PR for enabling SSL, which is probably a prerequisite for authentication: https://github.com/linkedin/datahub/pull/1794
