Initial update: Monday, 8th Aug 2016 5:30 PM PST

We are actively investigating an issue with Azure AD B2C. The JWT tokens issued by the service don’t have the ‘kid’ value pair in the headers. Some customers may experience errors while attempting to validate the signatures of tokens issued by Azure AD B2c.

  • Workaround: None
  • Next update: Before 6:30 PM PST

We are working to resolve this issue ASAP and apologize for the inconvenience.

  1. The issue has been mitigated at 9:08PM PST by rolling back the new token signing key that went active today. We are investigating the root cause and delay in mitigating this incident to prevent this from re-occurring in the future.
