What built-in role is required for a service principal to create an "APP Registration" ? I looked at the built-in roles and did not find one. https://learn.microsoft.com/en-us/azure/role-based-access-control/built-in-roles Any ideas ?

Hi @ Desmond Sindatry Creating an application registration does not require a built-in role, you need to grant the Application.ReadWrite.All application permission to your service principal, then use the unattended client credentials flow to obtain an access token and call the create application API endpoint.

Hi @Desmond Sindatry

This is no different, the Azure CLI uses MSAL as an authentication library, and its underlying is still implemented through the graph API. So when you log in with a service principal and create a new application registration, the service principal must be granted Application.ReadWrite.All application permissions.

Sorry, I was heads down on something else. I tried this out and still it does not work. My service principal has been granted all these API permissions including Application.ReadWrite.All (pic below). Then I tried the below steps to create a new app registration

az login --service-principal --tenant xxxx-3625-45b3-a430-9552373a0c2f -u xxxx-eb3b-4864-9512-5f403b41a037 -p xxxxx

az account set --subscription sas-ssod-sdmgt

az ad app create --display-name mas-observability-dev-hmr --available-to-other-tenants false

ERROR: Insufficient privileges to complete the operation.

What else am i missing ? How will the az ad app create using that service principal ?
