Sun OpenSSO Express is the stable builds from Sun's open source project OpenSSO. OpenSSO is a fork of Sun Access Manager code, and Sun Access Manager is discontinued ASFAIK.

As Sun already has names like Access Manager, Federation Manager, OpenSSO, Fedlets and Federated Access Manager, it comes as no big surprise that they announces yet another name to remember ;) Express.

OpenSSO Express is probably a big milestone in the identity history of Sun, and for sure worth exploring. Go get it at: opensso.org. I know I will, but I don't know when I have time for it.

I both hope and believe that the name Express reflects that the codebase is more lightweight and easy to install/configure than the prior AM product.
