Hello, we've been trying to integrate Okta with a self-hosted Moodle instance. I was able to get everything setup successfully but I'm still unsure of how to set up the Initiate Login URI. Users can login when going to Moodle and clicking on the sign-in button for Okta, however if they try to access the Moodle tool from the Okta page (Okta uses something called an "Initiate Login URI") it doesn't work. `admin/oauth2callback.php` was one of the endpoints we tried setting, since it's currently the sign-on URI, but that doesn't work either.
Here's a help article I found on explaining the initiate login URI from Okta: https://support.okta.com/help/s/article/How-to-make-the-OIDCOAuth-App-visible-in-Okta-dashboard-and-what-are-the-login-flows-available?language=en_US
It's also an OIDC/Oauth2 application.
If anyone has any ideas or can offer some guidance please help us out!
