The SAML 2.0 specification offers a lot of options and flexibility for the implementers of the standard which in turn adds to the complexity and the number of configuration options that are available both at the Service Provider (Elastic Stack) and at the Identity Provider. Additionally, different security domains have different security requirements that need specific configuration to be satisfied. A conscious effort has been made to mask this complexity with sane defaults and the detailed documentation above but in case you encounter issues while configuring a SAML realm, you can look through our SAML troubleshooting documentation that has suggestions and resolutions for common issues.
