Test Your CAS Application for Upcoming SSO Changes (Microsoft Entra)

Summary

Steps for application owners to test CAS applications during the SSO transition window.

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

  1. For applications you are responsible for, confirm ownership with your Director of Campus Technology or the SSO/MFA Modernization Project Team.
  2. Confirm the current status of the application:
    • Active (in use)
    • Inactive (no longer in use)
  3. Ensure the appropriate application owner is available to test.
  4. 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

  1. After 7:30 AM, close all browser windows.
  2. Reopen your browser to start a fresh session.
  3. Navigate to your application.
  4. Sign in using your UMS account.
  5. Confirm the application loads and functions as expected.
  6. 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
  • Description of the issue
