Silent Account Configuration refers to the process by which a user's computer is automatically configured so that it connects to OneDrive for Business. Silent Account Configuration requires either Group Policy, InTune, or making registry changes to a workstation. 

The preferred method to deploy the setting in a domain environment is Group Policy, which you can do by using the OneDrive for Business Group Policy Management templates.

The Group Policy template definition files are installed on a workstation where the OneDrive for Business sync client has been installed. By default, they are located in %LOCALAPPDATA%MicrosoftOneDrive<build>ADM. They need to be copied to a domain controller in the SYSVOL<domain>PoliciesPolicyDefinitions folder (the .ADMX file goes in PolicyDefintions, while the .ADML file goes in PolicyDefinitions<language>).

Once a Group Policy has been created for OneDrive, you can manage its settings. Take a look at the following screenshot, which shows Computer Configuration policies:
