Apereo is a non-profit open source software governance foundation. The CAS software is an Apereo sponsored project and is freely downloadable and usable by anyone. However, Apereo does not operate the systems of anyone using the software and in most cases doesn't even know who is using it or how to contact them unless they are an active part of the Apereo community.
If you are having problems logging in using CAS, you will need to contact the IT staff or Help Desk of your organization for assistance.
We wish we could be more directly helpful to you.
