The scope of the current OpenSSO Enterprise implementation is limited to SAMLv2–based single sign-on only. However, it is possible for you to extend this to other single sign-on protocols such as the Liberty Identity Federation Framework (ID-FF) and Web Service Federation (WS-F) specifications.
The existing implementation supports only simple HTTP GET and POST based mechanisms. However, you should be able to use the same APIs to do XML-based attribute transfer as well.
Integration with specific proprietary application server technologies such as WebSphere LTPA and WebLogic for single sign-on as well as single logout are not addressed in this document.
Limited single logout functionality is implemented. Logout from multiple Identity Provider applications and multiple Service Provider applications is not directly addressed in this document. The Identity Provider and Service Provider must implement logout appropriately to meet their own needs.
