Mattias, do you remember why the client tolerates an unset device mode in the
registration response?

[Mattias Nissler (ping if slow), 2016/09/12 07:01:21]

Not exactly, but I suspect we wrote the client-side code before the server
supported the field.

-      device_mode_ = DEVICE_MODE_ENTERPRISE;
-    if (!allowed_device_modes_.test(device_mode_)) {
+    if (device_mode_ != policy::DEVICE_MODE_ENTERPRISE) {
       LOG(ERROR) << "Bad device mode " << device_mode_;
       ReportResult(EnrollmentStatus::ForStatus(
           EnrollmentStatus::STATUS_REGISTRATION_BAD_MODE));
