Help with Okta setup

Your appsettings.json looks good.

The sign-in redirect URI should be this:

https://ud-dev.domain.com/authorization-code/callback

That’s formulated by concating the PSU URL with the CallbackPath:

"CallbackPath": "/authorization-code/callback",

I’m not aware of any configuration for the initiate login URI. The steps in the document were exactly what I took to get Okta working for me.
