Due to a failure in the authentication system, users attempting to access RDM Drive with their university accounts (SPS-ID or ECS-ID) were unable to use the service because the authentication page did not display correctly. Instead, the following error message was shown:  "The accessed application is not registered with this service"

We sincerely apologize for the inconvenience caused.
