[Aerogear-users] Keycloak - validate token on server

[Doug Drouillard]

I ended up forking aerogear and merging in an unmerged PR that exposed
Safari View Controller (I am targeting iOS 9+) and then also modified to
allow for passing of kc_idp_hint.

https://github.com/drouillard/aerogear-ios-oauth2

It is nice and clean and avoids the user experience issues that motivated
my original question. E.g. embedded views dont work with Google sign-in and
the external safari makes user answer an additional prompt (Open in 'app
name') plus risks leaving them in no-persons land if they cancel.

For my active account question I likely can just use the Admin API can
check outright for if user is enabled.

Still researching best Java client to use in my case as it seems like i am
in a bearer-only situation. The aerogear code is easier to follow as there
is not intermixing of session/server logic like the servlet examples I have
seen.
Verifying the JWT on local server is easy and likely good enough but I
believe there should be a way to verify it with the keycloak server if
desired using certificates/possibly open-id end points. I am working in a
high fraud situation so need all options available.

Will update this thread as they appear in Google search results.
