InCommon Federation Protocol and Software Guidelines

InCommon recommends and supports the following protocols, software systems, and versions.

Protocol	Level of Support
SAML 1.1, as profiled in "Shibboleth Architecture:  Conformance Requirements (Sep 2005)" and "Shibboleth Architecture:  Protocols and Profiles (Sep 2005)", available from http://shibboleth.internet2.edu/about.html.	Supported
SAML 2.0	Supported, for early adopters, see FAQ

Software	Level of Support
Shibboleth System 2.x and minor releases	Supported
Shibboleth System 1.3.x and minor releases	Supported, but not recommended for new installations. Instead use Shibboleth 2.0. Note that Shibboleth 1.3 will no longer be supported after June 30, 2010.
Shibboleth System 1.2 and earlier releases	No longer supported
Other SAML-based, federated identity management systems	Other software systems  interoperable with SAML 1.1 and the Shibboleth architecture specifications (Sep 2005) may be used; however, such systems are not actively supported by InCommon customer support. Active support for systems other than Shibboleth will be considered as participant needs arise.

InCommon provides accurate metadata for all supported software systems listed above. Changes to supported versions are announced on this Web page and are made under the advisement of the InCommon Technical Advisory Committee, whose members are listed on our about page.
