Problems with Synology Active Backup for Business Agent

You probably need to reach out to the vendor for advice and guidance. This sounds like a quark or issue with their application, not with macOS or JAMF. They are probably needing past disk encryption, which is a lot easier said then done.

FileVault uses tokens, and there are only a couple of ways to get a FileVault Token.

• The main method to get a FileVault token is to have the account on the device when FileVault is enabled, this is the only "automated" way to get a FileVault token. 
• Any Account created AFTER FileVault has been enabled will need a FileVault Token manually granted to it. In order to grant a FileVault Token, you need the username and password of a current FileVault Token holding account. This can be scripted, if you have the credentials of a FileVault Token holding account.

I am guessing the issues you are seeing involving FileVault involve the application needing a FileVault/Secure Token. The only way to grant a FileVault/Secure Token is if you know the username and password of an Account that already has a FileVault/Secure Token.

Hello AJ

The logged in user has a secure token. The application tells me to enter the credentials of a filevault enabled user.

On a machine without enabled remote management it works fine. Only with Jamf managed devices it doesn't work.

Synology said, it's an issue with Jamf. You tell me it's an issue with Synology..

I will disable filevault and test it again, if the creation of the user still fails I know it's an issue with Synology. If it works I know it's an issue with filevault or Jamf.

Kind regards
