Issue/Introduction

Problem was detected with SSO over Kerberos in AWI:

After the login, the user is able to navigate within the application, as long as the same browser tab is being used.

But when the user tries to open a new browser tab or reload the page (F5 hotkey), only a empty page is being returned.

The AWI shows the following error:
