Aravind Putrevu's blog post outlines the process of integrating Auth0, an identity service provider, with Elastic Cloud to enable Single Sign-On (SSO) for Kibana using the SAML protocol. The integration allows users to log into Kibana with their Gmail, GitHub, or Microsoft accounts without additional credentials. The process involves setting up an Auth0 application with SAML add-on, configuring necessary URLs and metadata in Elastic Cloud and Kibana, and enabling social login connections. While the blog provides a detailed step-by-step guide for this configuration, it also suggests consulting additional resources on the SAML protocol and other security protocols like OpenID Connect and Kerberos for further exploration.
