'X-M2M-Origin' header in OM2M [message #1867077]

Hello,
I am trying to develop an IoT device which will be talking to an oneM2M IN-CSE. I need to implement oneM2M over MQTT. The topic for MQTT is as follows:
/oneM2M/req/<originator>/<target-id>/<serialization-format>
The <originator> is present in 'X-M2M-Origin' header according to the article below:
https://wiki.eclipse.org/OM2M/one/MQTT_Binding
Where can I find this X-M2M-Orign header and the originator?

Dear Rohit ,

The oneM2M requests that your IoT device will be sending need to have a known "Originator". Typically, it's the name of the AE that represents your device under the CSE's Resource Tree. This name is checked against the control access policies (this implies that an ACP for this AE has been created first).

For example, with default settings, OM2M declares an ACP with full privileges for the originator "admin:admin" (MUST BE modified before going in production).

To sum up; the originator is the name that identifies the sender of the oneM2M requests. For any name that you will want to use, an ACP for this "name" must be created first (with the appropriate privileges)

Hope that will help.
