Self-Service Says My Username Doesn't Exist
Cause of Issue
This error is a back-end issue due to older accounts that have not been automatically enrolled with the Self-Service portal. Previously, with older version of Self-Service, students were required to enroll their information with the portal during their first sign-in.
This process was turned into an automatic one with the latest versions of Self-Service, where all enrollment is done on the back-end of the process.
Resolution
Create a ticket with the Help Desk and they will manually enroll you within Self-Service so that you can proceed with any Self-Service services.
