Outlook plugin and SAML for On Premise Instance

Hello,

We are facing a problem related to the Outlook Plugin for On Premise Instance : as far as I understand, the plugin is not compliant with SAML authentication because it requires Sugar Identity (Cloud Only).

I don't know if one of you already find a solution to solve that ? Is there a way to "re-route" the query ? Or maybe there is a way to use Sugar Identity out of Sugar CLoud ? 

Any idea is welcome.

Fred
