Has anyone successfully used SImpleSamlAuth and SimpleSamlPHP with MediaWiki 1.27? I'm working on building a 1.27 replacement for an existing 1.25 environment and I can't get authentication working for the life of me. Using SamlTracer I can see that the 1.25 environment sets a session cookie before SimpleSaml redirects to the IDP. In 1.27 that cookie is not set. The other difference (and the main symptom/cause) of my login failure is that my session ID changes between being redirected to the IDP and the response being sent back to SimpleSaml. This causes a NOSTATE error.
Just wondering if anyone else has ran into this, or if i've done something stupid in my config that I just haven't noticed.
