Hi All,

We have a project called the Enterprise Sign On Engine (
http://esoeproject.org ) which is an Apache 2.0 licensed platform for
authentication, authorization and accountability for both internal
enterprise users and federated contexts.

With ESOE integrated into Open XChange you would automatically get the
benefits of using openID and Shibboleth in your web tier. Open XChange 
would also get our
ability to do true single sign on from Active Directory enabled
enterprise clients in the web tier. We also have a very powerful XACML 
based
authorization engine which allows some really unique flexibility in
providing access control to content.

All said and done we are trying to provide a clean general purpose
solution to identity and federation that can be used across many
products without needing to continually reimplement this kind of thing.
You don't have to write your own database for every application you
create we believe it should and can be the same way with identity.

We intend to support further technologies in the future such as Yahoo's
BBAuth and Microsofts Identity Card. The really neat thing is that the
application side doesn't need to be changed at all when these new
options come on board for end users.

Please take a look around the website and I would really like to talk
further with you guys if there is an interest in doing some work together.


regards,
Bradley
