SAML IdP Proxy

[Andrew Owen]

We have a requirement for cross-federation interoperability (allow IdPs in one federation to authenticate its users to access SPs in another federation), after some poking around I stumbled across this link which introduces the concept of a SAML IdP Proxy: https://spaces.internet2.edu/display/GS/SAMLIdPProxy

This sounds like a promising approach to enable cross-federation interoperability but I'd like to learn more.  Is there any documentation available about how to implement this pattern using the Shibboleth IdP and SP? Can you share any examples of where the SAML IdP proxy is implemented in the real world?

I appreciate any additional detail you're able to provide.

Thanks,
-Andrew
