If you try to embed DELMIA Apriso screens in 3DLean, you should be able to see the Apriso login screen. However, when you try to log in by using an Apriso user, the login process may fail and the page is reloading and looping back to log in page. This issue is caused by cookie's cross origin restriction (Apriso cookie is blocked) by newer version of browser like Chrome, Edge and Firefox. 

By adding additional configuration to Apriso web server's configuration file, this issue can be solved.
