First of all I want to pose my question and elaborate further down this post:
How should it be done to add an administrator to Connected Factory solution accelerator? https://learn.microsoft.com/en-us/azure/iot-accelerators/iot-accelerators-connected-factory-features
The resource downloaded from here is used. https://github.com/Azure/azure-iot-connected-factory
It was possible to develop to a subscription of a target using "build.ps1". But only the account which developed is an administrator, and the way to make the other accounts an administrator isn't understood. How should it be done to change the setting?
