When InCommon was created 10+ years ago, it was an explicit goal to keep the bar for membership and operational participation as low as possible. This helped to grow the Federation to its current size. However, this has also hindered interoperation. Members cannot make any real assumptions about policy, practices, and the supported functionality at other member sites when attempting to interoperate. Both IDPs and SPs suffer from this problem.

Charter

1. Develop a set of proposed updates to the SAML2int specification in order to better facilitate interoperability.
2. Produce a list of recommended/required deployment practices for both IdPs and SPs that would increase interoperability and security within the InCommon federation. The intention would be that sites following these practices would, to the extent possible, interoperate by default.
3. Develop a set of proposed updates to the SAML2int specification in order to better facilitate interoperability.

The Interop Issues List created in FedInterop Round 1 can serve as point of departure for this work.
