Web Single Sign-On Implementation Using the SimpleSAMLphp Application

摘要

Web Single Sign-On is a feature offered by web applications that have a trust relationship, not necessarily within the same company. The goal of Web SSO is to provide authentication information for all the web application in the trust relationship, without requiring the user to login in each web application. SAML 2.0 is the standard that defines the framework in order to achieve Web SSO and identity federation in a web context. In order to make a Web SSO implementation, we used the open-source SimpleSAMLphp library, which implements the standards of SAML 2.0 and provides functionality for the two scenarios: SAML – Service Provider and SAML – Identity Provider.
