Azure Ad terraform Config, where does the Client Id come from? - azure-active-directory

Question

I have the following terraform config.
# Terraform Block
terraform {
required_version = ">= 1.0.0"
required_providers {
azurerm = {
source = "hashicorp/azurerm"
version = ">= 3.0"
}
}
}
# Provider Block
provider "azurerm" {
features {}
}
# Datasources
# https://registry.terraform.io/providers/hashicorp/azuread/latest/docs/data-sources/client_config
data "azuread_client_config" "current" {}
output "object_id" {
value = data.azuread_client_config.current.object_id
}
output "client_id" {
value = data.azuread_client_config.current.client_id
}
output "tenant_id" {
value = data.azuread_client_config.current.tenant_id
}
When I plan and then apply, I get the following output.
Outputs:
client_id = "04b07795-8ddb-YYYY-bbee-XXXXXXXXXXXX"
object_id = "3603657a-34b8-YYYY-b7df-XXXXXXXXXXXX"
tenant_id = "35b02984-c026-YYYY-8cb3-XXXXXXXXXXXX"
I could figure out where object_id and tenant_id come from. See below, I have screen shots to show.
But I could not figure out client_id source.
Here is where object_id and tenant_id come from.
First the object id.
And now the tenant id.
So the question again, what is this client id and where does this come from?
Update
I dont see anything in the enterprise applications tab of the AD. What am I missing?

Answer 1

I checked the clientId that resulted from the below output
data "azuread_client_config" "current" {}
output "object_id" {
value = data.azuread_client_config.current.object_id
}
output "client_id" {
value = data.azuread_client_config.current.client_id
}
output "tenant_id" {
value = data.azuread_client_config.current.tenant_id
}
If I check with that Id in azure Ad applications, it the Microsoft Azure CLIs applicationId
This client ID or (application ID) is the appId of the one which
used to authenticate to ( i.e; the application used for delegated
authentication.) or is linked to the authenticated principal.
As in azure to deploy Terraform configurations , we need to complete
authentication.
Terraform can actually use the current account logged into Azure CLI
for authentication which is my case.
