We are ultimately trying to use PingFederate as our IDP (to get ActiveDirectory auth).
For the logout testing locally right now, we are just using your PHP docker IDP. We get
a successful logout – but then don’t redirect correctly it seems.
Will test more with Firefox and see if I can find anything useful there, thanks!
One other strangeness as a shot in the dark – our local Samly setup seems to work for login – using your PHP docker, but when we put things in production we get ERR_SPDY_PROTOCOL_ERROR right off the bat.
We think possibly our umbrella project docker deployment is not getting the right files for SAMLY because the paths from config at compile might not match prod…
Thanks for the assistance! I’ll report back with anything else we figure out!
