2021/07/19 Single Sign-On (SSO) Failure for Some Services (Restored)
Category:
Disability（障害）
From 22:30 on July 17th, 2021 to 23:30 on 18th, there was a problem with single sign-on (SSO) to the following services
- Zoom
- Adobe ID
Two weeks before the expiration date of the digital certificate used for SSO, a new digital certificate was automatically issued, and the positive and negative certificates were switched, but users were unable to log on to Zoom, Adobe, and other systems that do not support the positive and negative switching.
We manually switched to the new certificate at around 23:30 on the 18th, and the problem has been restored.
We apologize for any inconvenience this may have caused.
