OpenAM
OpenAM is an open source access management, entitlements and federation server platform.
ForgeRock announced in February 2010 that they would continue to develop and support OpenSSO from Sun now that Oracle has chosen to discontinue development on the project. ForgeRock has renamed the product to OpenAM as Oracle retains the rights to the name OpenSSO.
ForgeRock has announced that they will continue delivering on the original Sun Microsystems roadmap.
