Authentication and federation application supporting several protocols

 simpleSAMLphp, with its support for several authentication mechanisms
 and federation protocols, can be used for local authentication, as a
 service provider or identity provider. It currently supports the
 following protocols:
 .
  * SAML 2.0 as a Service or Identity Provider.
  * Shibboleth 1.3 as a Service or Identity Provider.
  * A-Select as a Service or Identity Provider
  * CAS for remote authentication
  * OpenID as a Provider or Consumer
  * WS-Federation as a Service Provider
 .
 Further authentication providers can be added in form of modules. Other
 features are protocol bridging, eduGAIN compatibility, attribute mapping
 and attribute release consent.
