Body
This article explains how CAS (Central Authentication Service) application owners should prepare for and complete testing during the transition to the new Single Sign-On (SSO) system using Microsoft Entra.
Instructions
Before You Begin
- For applications you are responsible for, confirm ownership with your Director of Campus Technology or the SSO/MFA Modernization Project Team.
- Confirm the current status of the application:
- Active (in use)
- Inactive (no longer in use)
- Ensure the appropriate application owner is available to test.
- If the owner is unavailable, assign a backup tester.
INFO: Testing helps confirm that your application will continue working after the SSO system changes in May.
Testing Window
WARNING: Testing can only be done during this testing window.
- Date: Sunday, April 12, 2026
- Time: 7:30 AM to 9:30 AM EST
Steps to Test Your Application
- After 7:30 AM, close all browser windows.
- Reopen your browser to start a fresh session.
- Navigate to your application.
- Sign in using your UMS account.
- Confirm the application loads and functions as expected.
- Check for:
- Login failures
- Error messages
- Unexpected behavior
WARNING: If you do not restart your browser before testing, cached sessions may affect results.
Reporting Issues
If you experience any issues:
Please include:
- Application name
- Application login URL

Why This Matters
Testing ensures your application will work correctly when the new SSO system (Microsoft Entra) goes live.
WARNING: Applications that are not tested may experience login issues after the transition.
