Failed to activate encryption on high sierra

Question

We're having this new issue. Apple finally started shipping macbooks with High Sierra and now we're trying to install safeguard 8.0.3 on our first HS machine and we're getting an error after we drag the client configuration zip file. 
 
 Safeguard Management Center Version 8.00.2.16 
 Machine OSX version 10.13.1 
 Safeguard Client version: 8.00.3.9 
 Cert is SHA2 256 
 Installing as domain user 
 Filevault is not enabled 
 I know there is an article based off of this error 
 https://community.sophos.com/kb/en-us/122152 
 I tried the step 3. Use the following command " fdesetup changerecovery -personal -verbose " and it comes back saying "Filevault not turned on" 
 
 I created a new client config package just to see if that was the problem but it's not. Same package and client works on Sierra. I reached out to support multiple people have remoted onto the machine and server and they can't seem to figure it out. My question is, is anyone else able to install a fresh copy of safeguard on high sierra.

We are aware of an issue with Apple macOS 10.13.x that by using an Active Directory user you might not be able to get FV2 enabled. 
 And if you enable FV2 with a local macOS admin and later you try to add the Active Directory user - the system preference pane might get crashed. You can check the local system.log and search for "fdesetup". We expect that you will find an fdesetup activation error 38 or similar. So please get in contact with Apple support and check with them what can be done to get FV2 enabled by using an Active Directory user object incl. using the mobile account profile for this user.
