I'm using Azure Active Directory (Premium, with full MFA). I've set up a VPN gateway and would like users to be able to authenticate to it using their Azure AD username and password (instead of certificates).
From everything I read, this should be possible - Azure MFA provides a RADIUS server, and the Azure VPN Gateway can connect to a RADIUS server.
But I can't figure out how to do fit - in the gateway's P2S configuration, I need to provide an IP address and a secret. Where would I get those for the Azure AD MFA server?
