Maintenance: Shibboleth Authentication Service (Single Sign-On - SSO), 26-Aug-2026, 8 p.m. - 10 p.m.

On August 26, 2026, from 8:00 p.m. to 10:00 p.m., maintenance work will be performed on the Central Single-Sign-On (Shibboleth) [1].

During this time, disruptions to Single Sign-On authentication may occur. This will affect all applications that use Single Sign-On authentication, such as:

• Webmail (OWA)
• Self-Service Portal (SSP)
• eduVPN (VPN login)
• Intranet / WebCMS
• and many more.

As part of this maintenance, the input forms for two-factor authentication [2] will also be revised. Existing tokens and recovery codes remain unchanged.
