Hi there,  
I have installed a single node node on linux (role: monitoring node) (v. 7.8.1 // elastisearch + Kibana + redis)  
If in the elasticsearch.yml I give this:  
xpack.security.enabled: false  
then for example a curl for health with the elastic or the kibana user works fine.  
There is an active license installed.  
elected-as-master has joined noids - all is well

As soon as I put this in:  
xpack.security.enabled: true  
after restart troubles do start and elasticsearch tells me:  
security index is unavailable  
And yes: there is no such index:  
green open .monitoring-es-7-2021.06.02 1a0nXAroRW-UP5AO-g\_A\_w 1 0 473 78 910.3kb 910.3kb  
green open .triggered\_watches f-bbjo5NTRu29ab2P5ZVVw 1 0 0 0 8.8kb 8.8kb  
green open .monitoring-alerts-7 I\_378dIqTfmTbBmvX5e5Hw 1 0 1 0 6.2kb 6.2kb  
green open .watches Uv3DWVgoRJKnvMfv5jlSjg 1 0 6 12 251.2kb 251.2kb

I also miss the .kibana index (since kibana refuses to start).  
Now a curl on health gives:  
**unable to authenticate user [elastic]**  
So: why this behaviour? How can I solve this situation? The security index needs to be created, but this is normally done automatically!

cheers  
Stefano

Did you used [elasticsearch-setup-passwords](https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-passwords.html)? If you would use a multi node cluster, i would also highly recommend to use TLS for internode communication, I had some problems when not using it.

A used the mentioned script and the results where positive - thanks!
