In the Deployment Scenarios section under the Sharepoint Guides (https://help.okta.com/en/prod/Content/Topics/DeploymentGuides/Sharepoint/Guide/deploy-scenes.htm) there is a section called Mixed Authentication Provider.

In that section, it mentions that an "admininistrator can extend SharePoint to use programmatic methods of guiding the user to the correct authentication method (based on IP for example)."

My question is, has anyone been able to figure out how to do this? We currently have scripts running that authenticate to sharepoint using Winodws auth and we are unsure how to set it up the way the example shows.
