Enable Enterprise Connections
You can enable enterprise connections for applications using the Auth0 Dashboard. To enable your enterprise connection, you should have already set it up.
Go to Auth0 Dashboard > Authentication > Enterprise, and select the connection type to view.
Select the name of the connection to view.
Select the Applications view, and enable or disable the connection for the appropriate application(s).
When you set up your enterprise IdP connection, remember that the connection parameter passed to Auth0's /authorize, /whr, or /wsfed endpoint will redirect to the upstream IdP unless it's connected via database or Active Directory.
