I am new to Elastic Stack. We are looking at embedding Kibana dashboard inside our application. We are planning to go with the Basic version of Elastic stack(free version) to begin with. However, we want to have the authentication option enabled. I am aware that it is part of the Basic version now. But, I do not want the user to login(again) separately to Kibana dashboard console to access that instance inside our web application. When I explored the forums, they say we can have reverse proxy option to handle this scenario, but it is not the ideal solution for us. We would like to go for SSO model. Came to know that SSO is part of the higher license model. I would like to know if we can buy only the SSO module of security alone as a license so that we will use Basic + SSO to solve our problem. Appreciate your detailed response on the same. Also, the pricing model for SSO option would be great.
