Why are some students unable to access their library account?
When the user signs in via SSO, they are redirected to the OneSearch home page.
Answer
Only current students and employees can access their library account via OneSearch. If someone is not currently enrolled in classes, or they are a temporary employee who is not currently working, or adjunct faculty without current course assignments, they might be able to get through the Single Sign-on page, but instead of seeing their account they will be redirected to the OneSearch home page.
If you are able to access user records in Alma, you can check the user's expiration date to confirm--most likely it is in the past.
If someone in this situation needs to find out what items they still need to return, they should contact the relevant library's circulation desk.
