It’s been six days since my original post and no one has responded. So no one in the community has attempted to use Duo’s Generic SAML Service Provider - Single Sign On application with ANY on premise Microsoft product?! I know I stated SharePoint in the original message, but just to get the conversation started I’d be happy to learn from anyone with experience using this application with any on-premise Microsoft server product that has a web server interface (e.g. OWA). Should this question be for Duo’s support team instead?
