SAML AzureAD support on Linux

Really need SAML 2.0 support for AzureAD integration on Linux. Documentation isn't even clear that this isn't supported on the AzureAD configuration page (there's a warning at the top of the previous, overall "SAML" documentation page). Apparently to do SSO with AzureAD for my techs I'm stuck migrating my server and paying 3X the cost of a Linux box that's worked well for us since version 4 of ScreenConnect...
