We have several apps which are built using .NET are running in VMS(on-prem)
All apps will be registered to Azure AD.
Can we use user managed identity to access key vault form these on-prem apps
Thanks in advance
No, you cannot use a Managed Identity from on-prem apps.
[...] a managed identity is a service principal of a special type that may only be used with Azure resources.
Source: What are managed identities for Azure resources?
To see a list of resources currently supported, see Services that support managed identities for Azure resources.
You can, however, use a Service Principal to connect to Key Vault from an application running on-premises.
To do so, Use the portal to create an Azure AD application and service principal that can access resources.
For Service Principals, authentication can be done in two different ways: password-based authentication (application secret) and certificate-based authentication. Using a certificate is recommended, but you can also create an application secret.
To access resources that are secured by an Azure AD tenant, the entity that requires access must be represented by a security principal. This requirement is true for both users (user principal) and applications (service principal). The security principal defines the access policy and permissions for the user/application in the Azure AD tenant. This enables core features such as authentication of the user/application during sign-in, and authorization during resource access.
If you cannot use managed identity, you instead register the application with your Azure AD tenant, as described on Quickstart: Register an application with the Azure identity platform. Registration also creates a second application object that identifies the app across all tenants.

I am getting the below error message when my Application (A) is trying to access another application (B) which is hosted in a different Tenant. Both applications have been registered to support multi-tenant access (i.e Accounts in any identity provider or organizational directory (for authenticating users with user flows) within their respective tenant. The microsoft outlook account I am using is associated with both tenants. What am I missing?
'AADSTS650052: The app is trying to access a service 'xxx-xxxx-xxxx' that your organization 'xxx-xxx-xxx' lacks a service principal for. Contact your IT Admin to review the configuration of your service subscriptions or consent to the application in order to create the required service principal.
In order for an application to authenticate with a tenant, a service principal representing it must exist in that tenant. For multi-tenant apps this is created when you go through authentication to that app on the target tenant. So you need to do a login against your app with the target tenant as the authority.
I know that I have to create a service principal when I need an identity for an app that connects to Azure resources. But if someone asked me "Why not just create an AAD user and authenticate as that user?" I honestly couldn't answer besides "That's not how you do it.".
Can someone give me a proper explanation on why using an AAD service user instead of an app registration would be a bad idea?
Service principal is an application whose tokens can be used to authenticate and grant access to specific Azure resources from a user-app, service, or automation tool, when an organization is using Azure Active Directory
By using a Service Principal, we can avoid creating "fake users" (similar to service account in on-premises Active Directory) in Azure AD to manage authentication when you need to access Azure Resources
The Service Principals' access can be restricted by assigning Azure RBAC roles so that they can access the specific set of Azure resources only
So for better security purpose, we can use service principal instead of Azure AD User from an to authenticate and access Azure Resources.
Is it possible to manage users and groups using Terraform?
Operations such as MFA, user-types, Authentication methods, Registration, notification, User settings, group settings, and Device settings.
Is it possible to manage users and groups using Terraform?
Yes, you can use Terraform to integrate with Azure AD and manage users and groups in Azure AD. At the same time, Terraform supports a number of different methods for authenticating to Azure AD.
Please see:here.
We are trying to connect to Azure service bus entity from "GO" language application & the integration with Azure service bus entity is possible by supplying either SAS token or Azure AD OAuth2.0 token which will be obtained via security principals. Technically I prefer security principals option rather than SAS token as it has security vulnerabilities.
How to acquire OAuth2.0 token from Azure AD using language like "GO" for which Azure AD SDK is not available?
Is it possible to make direct call to Azure AD REST APIs to access OAuth2.0 token? if yes some code sample would be helpful otherwise please suggest suitable options.
Here are available authentication methods for Go.
Also, you can make a direct call to get the access token.

I am not sure this is possible, but can Azure AD be trusted by a local on-premises domain?
I can see plenty of information on extending the local domain into Azure, but my requirement is more of less the reverse of this.
Ideally I would like the local domain to trust Azure AD, but as an alternative
could Azure AD DS be used to extend Azure AD into an Azure AD DS domain and then have a two way trust with the local domain?
I am not sure this is possible, but can Azure AD be trusted by a local
on-premises domain?
As I know, there is no way to make Azure AD be trusted by a local on-premise domain.
Azure AD is used for authentication for Internet-based services such as Office 365 and Azure, as well as much more, including Facebook and thousands of other services that are already federated with Azure AD (which mean they trust Azure AD without you having to do anything other than enable that application or service to be used by your users).
Your on-premises Active Directory can be synced to Azure AD by using Azure AD Connect (including password sync) and federation. This allows users on their corporate assets to log on with their AD account and when they access Internet services, such as Office 365, authentication with Azure AD just happens seamlessly via the federation, allowing access to all the different services that Azure AD is federated with.
Azure AD Domain Services provides managed domain services such as domain join, group policy, LDAP, Kerberos/NTLM authentication that are fully compatible with Windows Server Active Directory. You can consume these domain services without the need for you to deploy, manage, and patch domain controllers in the cloud. Azure AD Domain Services integrates with your existing Azure AD tenant, thus making it possible for users to log in using their corporate credentials.
