Version

Storage Type

Kubernetes

Installation Type

Official Helm chart

Expected Behavior

Logging into Dex with Microsoft as backend connector transforms the camelcase email from Microsoft AD correctly into a lowercase email. When the access token expires and a new one is issued using the refresh token, the email address should be transformed again. After refreshing the access token, Kubernetes API-Server doesn't authorize the token since the email doesn't match the RoleBinding anymore.

Actual Behavior

When the access token expires and a new one is issued using the refresh token, the email address is not transformed again.
