We have ES with custom realm that is accepting saml token and setting up user/roles based on the token.
Kibana with out x-pack works well as it passes on the saml toke in Authorization header to ES and it works really fine.
I tried to setup xpack as i want to setup monitoring ui, and look at how various ES/LS nodes are performing. I tried to keep this blog post as refernece and setup kibana. in my case there is no act as user as my custom realm is able to translate my token to Es user\role. But when i setup Kibana with Xpack in front, i always get to kibana login screen and authorization header (which has my token) is never sent to ES. I looked at logs and there are no errors. but the token is never sent to ES. I also tried to add the below configuration to kibana, but it does not seem to work.
Can you please help me with this configurations.
