Signing certificate expiration WARN alert
This event is sent daily for the last 30 days until the InforSTS signing certificate is
expired. Due to the criticality of the federated logins, this alert is issued daily unless the
identity provider is already updated with the new certificate. If the administrator fails to
update the identity provider connection, there is a possibility of issues with federated sign
in/sign out with your tenant.
The event includes expiration dates and thumbprint details about the expiring certificate. There is also a link to Knowledge Base Article ######This article provides information on the certification rotation exercise.
