Authenticate users using simpleSAMLphp
SimpleSAMLphp is a simple application written in native PHP that deals with authentication. SimpleSAMLphp supports several federation protocols, authentication mechanisms and can be used both for local authentication, as a service provider or as an identity provider
This plugin uses some hooks in WordPress's authentication system to bypass the normal login screen and authenticate using a simpleSAMLphp Service Provider (SP) instead. Note that logged-in state is still maintained in cookies, and user entries are created in the local database.
