Summary
Sun instigated the Liberty identity federation project five years ago, but along with other Sun-sponsored identity tools, Liberty received relatively little developer attention lately. In a recent blog post, Sun's Pat Patterson gives an update on Sun-sponsored identity projects, including OpenSSO, OpenDS, and Project Tango.

Sun's support of the Liberty identify federation framework received much attention four years ago, but few developers heard from Liberty since then. It turns out that Sun has open-sourced much of its identity management solutions, and also expanded those tools to provide interoperation with Windows authentication, as well as directory services.
From the directory up through access control and SSO to Web services, Sun is diligently working with the open-source community to build the tools to do the job. All three projects share the Common Development and Distribution License (CDDL), which renders it a snap for you to participate and incorporate the technology in your own work space.
The projects he discusses are:
OpenSSO, a single-sign-on API and framework
OpenDS, an open-source directory service written in Java
Project Tango, also termed Web Services Interoperability Technology (WSIT) that aims to bridge the gap between Microsoft and Java authentication and authorization technologies.
Of these projects, single sign-on (OpenSSO) is especially interesting to those who have to manage access to multiple Web sites. What solutions do you currently use to allow automatic login to multiple sites?
