Hi Team,
I need to enable authentication for Kibana 6.6.2. Could not find exact shield installable for this version. Could you please let me know the correct shield installable for this version. Also, I could see that x-pack is enabled by default for versions above 6.3. Does that mean that x-pack is open source now?

HI @harika.gudumasu,
Some feature of X-pack is opened in 6.x series but some features are paid. Please find below link for subscription details.

i dont think so that shield support 6.x series as latest version of shield is 2.4.6 which is compatible with 2.4.6.

i don't think you can use this shield version for 6.x series as in shield documentation clearly mentioned that compatible with 2.4.6.
You can use x-pack for the same under paid version.

Hi Harsh,
I am trying to check on installing X-pack for 6.6.2.
However it says as below.
"The following installation instructions are only valid for versions 6.2 and older. In versions 6.3 and later, X-Pack is included with the default distributions of Elastic Stack, with all free features enabled by default"
But I don't see any available within plugins of my elasticsearch and kibana folders.

Yes, x-pack is already installed in your version you dont need to install it.
You need to enable the license and use security feature.

Harsh, Is it mandatory to enable SSL/TLS before enabling authentication?
