OpenID Federation is an open standard from the OpenID Foundation for interconnecting multilateral IT federations. The standard has been under development for nine years and is now close to completion. This opens up new possibilities for the identity federations currently based on the SAML protocol, such as those used in the DFN AAI and eduGAIN.
An important milestone on this path was a three-day meeting of 30 experts and developers at end of April to test the interoperability of existing implementations. KIT was also represented at this meeting and was able to verify its own reference implementation created in the Go programming language with others. The test federation provided by KIT's SCC was very well received and commended. Other development teams were able to join this test federation with their infrastructure and thus verify interoperability with other implementations and components.
In addition to practical activities, there were also a number of smaller and larger discussions to address outstanding issues. This has enabled the specification to be taken a step further. After a long-running process, a final publication is now expected before the end of the year.
In addition to the main OpenID Federation specification, there will also be extensions. KIT will play a leading role in one of these extensions as part of the Geant Trust & Identity Incubator.
