The Liberty Alliance consortium has announced that products from HP, IBM, RSA, Sun Microsystems and Symlabs have passed testing for SAML 2.0 interoperability.

The vendors participated in the November 2007 Liberty Interoperable event administered by the Drummond Group.

All vendors also passed Liberty Alliance testing against the US GSA SAML 2.0 profile, meeting the prerequisite interoperability requirements for participating in the US E-Authentication Identity Federation.

Roger Sullivan, president of the Liberty Alliance Management Board and vice president of Oracle Identity Management, said: "Organisations worldwide are deploying SAML 2.0 applications to enable secure new business services, help meet regulatory requirements and provide consumers with better protection against online fraud and identity theft."

Liberty Alliance said that its November event was the first to conduct internet-based and full-matrix testing.

Internet-based testing allows vendors to participate in the same interoperability event from anywhere in the world.

Full-matrix testing requires each vendor to test with every other participant to ensure that testing mirrors real-world identity federation interoperability requirements.
