The https://ttunit.ZenUni.ac.uk/ttfitmain.php appfarm website was used for looking up the UDo roles for students.
That link has been replaced with a page in PeopleSoft students:
Please log into PeopleSoft https://students.ZenUniac.uk >
Compass icon top right >
Navigator >
University of ZenUni >
Service desk dashboard.
then go to the udo data tab and input the id number to see all their roles returned.
