This blog post provides a detailed guide on configuring a Security Assertion Markup Language (SAML) realm for role-based access control (RBAC) in Elastic Cloud Enterprise (ECE) environments using Auth0 as an identity provider. It begins by outlining the prerequisites, including the necessary ECE and Auth0 versions, and follows with step-by-step instructions for setting up the SAML realm. The process involves creating a new application in Auth0, configuring SAML settings to align with ECE requirements, and mapping user attributes and roles to ensure seamless integration. The post also highlights the importance of troubleshooting and adjusting logging levels to manage SAML authentication effectively. Finally, it emphasizes the benefits of using SAML for ECE RBAC, allowing users to log into the platform using an external identity provider, thus simplifying administration and enhancing security.
