Briefly, this error occurs when Elasticsearch fails to validate the SAML (Security Assertion Markup Language) signature due to incorrect configuration or mismatched keys. To resolve this issue, you can: 1) Ensure that the SAML configuration in Elasticsearch is correct and matches with the Identity Provider’s configuration. 2) Check if the public key certificate used for SAML in Elasticsearch matches with the private key in the Identity Provider. 3) Verify that the time on the Elasticsearch server is synchronized with the Identity Provider, as time skew can cause signature validation to fail.
