I have installed opensearch on docker containers using docker-compose file and trying to setup SAML SSO using PingIdentity.
There is one parameter required for SAML SSO in opensearch, which is exchange_key. I don’t know what this exchange_key is and where can I get this key?
Is it needs to be generated on IdP side or I can generate it using online HMAC tool(Free Online HMAC Generator / Checker Tool (MD5, SHA-256, SHA-512) - FreeFormatter.com). Does this key has some relation with IdP ? If yes, how to map it with IdP
Could you please help me here?
