It worked with a little bit of finesse. You have to login on the primary site and then you can switch between the different sites in the system. I was building a company intranet and the different sites had different permission sets and functions on them. So this worked out perfectly!
One thing to note is that I did have to create a Must-Use Plugin that runs when a login page is visited and then redirects the user to the primary site’s login page. Once Okta has finished the authentication the MU Plugin then takes over a redirects them to the content they were trying to access.
Let me know if you have any other questions.
