Connecting Entra ID to Fortigate for VPN authentication

[mattlesperance]

I have been working through the process of connecting our Azure AD domain to our Forticlient EMS Cloud and Fortigate to allow for using windows creds to authenticate to VPN as well as enable autoconnect when off fabric.

I followed the steps in the fortinet documentation and am able to attempt to sign into the VPN at my windows login screen but the connection times out. Using a Debug to see if there is traffic reaching the fortigate I see that my authentication request is hitting the fortigate but not being forwarded on to Entra. 

I have a ticket submitted with forticare but wanted to see if anyone else experienced the same thing

This setup has several components and it is impossible to troubleshoot it without access to the system and logs.
