Hi Chris,
Although the Shibboleth Identity Provider is a supported Single Sign-On experience when deploying integration in Office 365, it’s a third-party product. Therefore, Microsoft does not provide support for the relevant deployment, configuration, troubleshooting, best practices, issues and questions regarding the Shibboleth Identify Provider. Thanks for your understanding.
For this situation, any community members' sharing will be highly appreciated.
Best Regards,
Henry Huang
