MDM Enrollment Can't Be Completed on macOS Devices

We are experiencing an issue on several devices when attempting an enrollment to Mobile Device Management (MDM). The device is communicating, but it appears there is a problem with certificates that won't allow the enrollment to complete. Automated Device Enrollment (ADE, formerly DEP) enrollments do not work either. Failure to enroll in MDM is occurring on the following types of devices:
  • Big Sur M1 Architecture

  • Big Sur Intel Architecture

  • Catalina

Console log below of before, during, and after an attempt for MDM enrollment on a device experiencing this issue:
