Central Authentication Service (CAS) maintenance - June 10

Thursday, June 3, 2021

What is happening? Various deprecated security protocols and ciphers from the CAS service are being removed.

What is the impact? This change applies to the limited set of applications still using the CAS service. Please note that CAS is a deprecated service and this removal is essential to maintain the security of Waterloo credentials.

When is this happening? The CAS change will be implemented on Thursday, June 10 at 8:00 a.m.

Why is this happening? This maintenance is required to remove obsolete protocols from campus authentication systems.

Action you may need to take before the change: Review your CAS services to verify they can communicate using TLS1.2 and associated ciphers OR prepare to switch to ADFS.
