Hi,

I want to configure security in elasticsearch using company signed CA certificate.  
The CA certificate provided is a cert chain.  
Now, when i I am trying to create certificates for elastic nodes, it is throwing error: Expecting 1 cert but found 3.  
Version: 8.6.2

Can anyone please guide how to use certificate chain in elasticsearch?  
Please help!
