According this when you create an Azure Resource Manager service connection to a certain Resource Group, Azure DevOps connects with Azure Active Directory (Azure AD) and creates an app registration with a secret that's valid for two years.
Well, what exactly are the permissions given to this app registration over the Resource Group? Same than the account which is creating the service connection?
When you create a automated Azure Resource Manager Service connection in Azure Devops, it will automaticlly create a service principal in Azure Active Directory(Named: Orgname-projectname-SubscriptionID).
You could navigate to Azure Portal -> Azure Active Directory -> App registrations.
When using this automatic service connection in azure devops, azure sources are operated through this service principal instead of the account which is creating the service connection.
This service principal has the Contributor role in Azure Resource Group.
Grants full access to manage all resources, but does not allow you to assign roles in Azure RBAC, manage assignments in Azure Blueprints, or share image galleries.
You can search for the service principal name in Resource Group -> Access control to check its permissions
what exactly are the permissions given to this app registration over the Resource Group?
It is a Contributor role, also did a quick test for you.
Same than the account which is creating the service connection?
No, the account needs to be the Owner of the subscription, otherwise it will not have the permission to assign the role to the AD App i.e. service principal.

I have created an automated Service Principal from the service requests on Azure Devops with sufficient permissions. Now, when I am trying to create an artifact which is an ML model (registered) it is not auto populating the registered models and resulting in an error.
I am using a free trial Azure account and attempting to implement CI CD for ML. I turned my firewall off and attempted as well but still the issue persists.
It appears that the Service Principal is not assigned the role in the appropriate subscription.
You need to grant the service principal Azure subscription access permission:
Login Azure portal->All service->Subscriptions->click your subscription->Access control(IAM)->Add role assignment->assign the correct role to your service principal
Refer to Use the portal to create an Azure AD application and service principal that can access resources and Assign Azure roles using the Azure portal for details.
I found a link here which says:
There is no way to directly create a service principal using the Azure portal. When you register an application through the Azure portal, an application object and service principal are automatically created in your home directory or tenant.
My question is, Can a 'service principal' create another 'service principals' in Azure? If yes, how? and what all permissions required for this?
Please suggest. Thanks.
A service principal can create another service principal after being assigned either the corresponding MS Graph permission, or Azure AD role
MS Graph Permissions
Either of the permissions
Application.ReadWrite.All
Application.ReadWrite.OwnedBy

I cannot set Azure Active Directory Admin in Azure SQL Database for myself.

To set the as the Azure Active Directory Admin in the Azure SQL Server : You have to have the Owner role or the Contributor:
As, Azure AD is nothing but an identity store in Azure. Here we can
define users, groups, applications, and service principles. These
users can authenticate onto Azure and they can access resources that
are part of Azure subscription.
We can assign Azure AD roles to a user and these permissions are
normally given to manage the various aspects of Azure AD.
Role-based access control (RBAC), on the other hand, is used to authorise a user to use Azure resources.
For example, you might grant a user the ability to create a storage
account or manage resource groups by assigning them a role.
At the management group, subscription, resource group, or resource level, role-based access control can be implemented.
RBAC has three basic roles that apply to all resource types:
Owner: This role has full access to all the resources and can delegate
access to others.
Contributor: This role can create and manage all types of resources,
but can’t grant access to other users and groups.
Reader: This role can view existing Azure resources.
Here, is the way I am able to add, as the assigned role to me is Contributor Role.
Once you have the Owner or Contributor Role you will be able to add the Azure Active Directory Admin for the SQL server:
Background
I want to give an application ownership of several of my Azure Service Bus queues ... specifically, by granting it the Azure Service Bus Data Owner role.
The Azure Service Bus documentation says this is possible:
Azure Service Bus supports using Azure Active Directory (Azure AD) to authorize requests to Service Bus entities (queues, topics, subscriptions, or filters). With Azure AD, you can use role-based access control (RBAC) to grant permissions to a security principal, which may be a user, group, or application service principal [my emphasis].
(Source)
However, I can't find a way to do it.
What I've Tried
Registered the application in Azure AD.
Granted the application the user_impersonation permission on Microsoft.ServiceBus. (Application permissions is disabled [1], so I selected Delegated permissions and checked user_impersonation [2]. No idea if that's right. I posted another question a while ago about Application permissions being disabled, but the accepted answer of editing the manifest doesn't work in this case.)
In my Service Bus queue, selected Role assignments.
Clicked Add.
Searched for my application.
Issue
My application doesn't appear in the search results in Role assignments.
A service principal is the instance of an application in a given tenant. (Multi-tenant applications can have service principals in many tenants, all referring back to a single app registration.)
To grant an Azure role to an application, a service principal must first exist in the tenant. To check if the service principal for an app registration already exists in the same tenant where the app is registered (and create it if it doesn't):
Using the Azure portal:
Navigate to Azure AD > App registrations > (app) > Overview
Under the Managed application in local directory heading:
If you see a link with the name of the app, the service principal already exists.
If you see a "Create service principal" link, clicking it will attempt to create the service principal.
Using Azure CLI:
az ad sp show --id {app-id}
az ad sp create --id {app-id}
Using Azure AD PowerShell:
Get-AzureADServicePrincipal -Filter "appId eq '{app-id}'"
New-AzureADServicePrincipal -AppId "{app-id}"
I am deploying a standard ASP.NET MVC application to an Azure App Service using a VSTS build and release definition. The VSTS instance and the target Azure subscription are on separate Azure accounts/subscriptions so we have create a Azure AD application and Service Principal account to authorize the deployment.
When adding the Service Principal account to the subscription, it wants us to assign a role.
What is the best and least privileged role that can be used to deploy the site?
When add Azure Resource Manager Service Endpoint, it mentions:
A new Azure Service Principal will be created and assigned with
"Contributor" role, having access to all the resources in the selected
subscription.
So, the Contributor role is better.
On the other hand, to configure Azure RM service endpoint, you must be a member of the Global Admin role in the directory. More information: Insufficient privileges to complete the operation.
