SAML-based authentication is an XML-based standard for exchanging authentication and authorization data between parties, specifically between an Identity Provider (IdP) and a Service Provider (SP), in this case, Couchbase. The integration of Couchbase with a Security Assertion Markup Language (SAML) IdP enables robust authentication mechanisms. Single Sign-On (SSO) integration offers advantages such as centralized user management, multi-factor authentication, reduced credential management, and enhanced security through the use of digital signatures. Understanding SAML's fundamental concepts is crucial for configuring SSO between an Identity provider and Couchbase, including verifying SAML requests and responses, checking logs, using debugging tools, testing with a single user, and ensuring proper attribute mapping configurations. Troubleshooting common issues such as invalid SAML responses or assertions, attribute mismatches, time skew, logout issues, and username extraction problems is essential for achieving successful SSO integration.
