@sberyozkin sorry, I know the issue is assigned to you, but I was curious on seeing it in action and spent some hours trying to make it work :)

Hey @gastaldi, thanks a million for giving it a try, appreciated. Nice space optimization in the catch block too 👍

I knew this integration had to be done at some point due to the earlier commitment which is why I opened this issue but I only had some images for the docs prepared :-), I'll push some docs update a bit later on.

FYI, I believe you can optimize since they support OIDC discovery, see https://www.linkedin.com/oauth/.well-known/openid-configuration, so let me suggest some minor updates

@gastaldi Hi George, I suggested to remove a few configuration lines, if you'd like, please ignore them, and remove all those line as a single block. Please test the proposed config update when you will have time. Please also add a pair of tests in OidcUtilsTest (to confirm remaining properties are set as expected and that each of them can be overridden, copying 2 Google tests there would probably be easiest for this case). I can follow up then with the doc update

@sberyozkin thank you! I just tested locally and your changes worked like a charm! I'll add some tests and ping you again when it's ready
