Okta Login With EPiServer

I’m trying to incorporate Okta with an EPiServer implementation. I have followed the ASP.Net MVC tutorial, and I’m able to use Okta for our users, however, EPiServer does use Forms authentication to get into their CMS Editor site. Using Okta breaks this since Okta does not want to use Forms Authentication. Has anyone run into this scenario where one section of your site, you have users you want to authenticate using Okta, and another section where you want to use Forms Authentication? I have looked around for solutions and I’m not seeing much on the subject. Any help is appreciated.
