A flexible and comprehensive open source, cross-domain, attribute-based web single-sign on system based on SAML 1.x and 2.0. Built on the OpenSAML libraries, a Java-based identity provider and native (C++) service provider are provided. The identity provider supports pluggability of both authentication and attribute sources and supports most of the core SAML SSO profiles and bindings. The service provider supports most popular web servers and enables seamless and loosely coupled integration of authentication and attribute data with applications without programming to product-specific APIs.

Open source libraries in Java and C++ providing core message, binding, and profile classes for implementing applications based on SAML 1.0, 1.1, and 2.0. Extensive design integration with the native Java and C++ programming models is provided. OpenSAML is a low-level toolkit that does not by itself implement full SAML profiles such as single sign-on, but can be used to simplify the implementation of such profiles. Provided under the standard Apache 2.0 license for use in any commercial or non-commercial code.

Symlabs Federated Identity Suite delivers the flexibility to create an identity management solution with Single Sign-On and Single Log-Out for nearly any environment. It is fully compliant with SAML (1.0, 1.1, & 2.0 including GSA profile) plus open Liberty Alliance standards (ID-WSF 2.0 & ID-FF 1.2), and also provides support for WS-Federation 1.0.
