In the December 16th update, we enabled Use Email as Username option for the PUT /manage/v1/user/{id} API. This change, where the Use Email as Username option is enabled, may impact Single-Sign-On if the user email field is not mapped in provisioning settings for your SSO configuration.
To avoid SSO issues, please ensure that user email is included when sending information from your Identity Provider to Docebo through Single-Sign-On provisioning.
