Understanding SAML and OAuth2 in Drupal
The Specbee blog post titled "SAML and OAuth2 - What’s the Difference and How to Implement in Drupal" by Manish Saharan explains the distinct purposes and implementations of SAML and OAuth 2.0 protocols in Drupal.
Both are used for authentication and authorization but serve different functions: SAML facilitates Single Sign-On (SSO) using XML-based assertions for user identity across domains. OAuth 2.0 authorizes third-party applications to access user resources without sharing credentials.
Drupal integrates well with both protocols, using modules like miniorange_saml for SAML and OAuth2 Authentication for OAuth 2.0. The post details the implementation steps for each protocol, including configuring service providers and authorization servers, ensuring secure access, and managing permissions within Drupal.
