We want to integrate OKTA as an IDP for Azure AD. Our requirement is when a user tries to access the application. They'll be challenged with a login page, which will be validated by Okta. Post this authentication, the authorization will be taken over by Azure and upon successful authorization, user will be shown a landing page of application. I checked following links to setup IDP in Azure AD but didn't come across detailed steps/procedure.

I recently did this with the Office 365 app integration. Office 365 is backed by Azure AD and you can sync users into it without an Office 365 license but authentication etc still works through the Azure AD directory. The automatic WS-Fed support worked well for this. As a side rant, the Okta documentation on this is not clear at all - I also had a separate support person tell me I needed to do it when an on-prem Okta AD agent connected to Azure AD to sync the accounts. Sigh.
