Pure Azure AD SSO authentication with Silverline

Hi,

We're trying to integrate SIlverline with Azure AD but haven't quite got it to work correctly. It appears that Silverline passes the autentication to Azure AD and this does complete successfully but Silverline then simply reports "Could not authenticate you via SAML because "Invalid Token". My guess is we need to map the correct attributes in Azure AD to send back to Silverline in the SAML response but cannot seem to find anything.

There is no on-prem AD or AADDS available - it's just pure Azure AD.

Has anybody done this and would be able to share what they did.
