> Whenever any API call fails with status 400 and message string that starts
> with java.lang.IllegalArgumentException: Missing KDC administrator
> credentials. or java.lang.IllegalArgumentException: Invalid KDC administrator
> credentials., present the user with a popup (that has save button) asking for
> admin principal and admin password. Once user enters principal and password
> and hits on save button, dismiss the popup and execute the API call to save
> it as session attribute (similar to createKerberosAdminSession function).
> Once this session call succeeds then again trigger the original API call that
> gave the exception.
> The authorization failure that can happen on any API call
