How to automate user assignment for ABM-enrolled devices?


iOS devices enrolled through Apple Business Manager (ABM/ASM), must be assigned users in order to allocate devices. Users can be assigned to each device either individually or in bulk by adding a CSV with the user details. This process can be time consuming and cumbersome, when the device user is to be reassigned. MDM resolves this by automating user assignment for devices enrolled through ABM as explained below:


  1. Configure Active Directory(AD) in MDM.
  2. When configuring ABM, enable the option Authenticate and auto assign users on device activation. If ABM has been already configured, modify the existing settings to enable the option.
  3. Enroll devices as explained here.
  4. When the device is being setup, provide the user name as domain name\user name
