When creating virtual machines, there is an option to create a managed identity for the machine for authenticating to other Azure resources such as storage accounts as referenced in the following Microsoft documentation.
https://learn.microsoft.com/en-us/azure/active-directory/managed-identities-azure-resources/
I have a virtual machine that runs IIS FTP service. I'd like to run the windows service as the managed identity so that it can access the storage account used for the ftp root directory, but I can't find a way to successfully specify this managed identity principle under the "This Account" area of the Log On tab of the service.
Is it possible to run a windows service within an Azure VM using the managed identity of the VM assuming the system assigned managed identity has been turned on? If so, when running the service as a specific user, do you format it like you would a regular managed service account by appending the $ at the end with no password?

So what I need is a remote/cloud Windows Server that I can connect to using RDP (or another remote connection program) where I can create users, groups, basically everything I could do with an on-premises Server instance. What I need though is to be able to setup all the office computers to authenticate through the cloud AD. I have no clue how to do this. I cannot have a Server running on-premises, period. Just need something where I can connect each computer to the remote domain/forest, hopefully using an IP to the server, and then have the employees be able to logon to any domain-connected PC using their credentials. Thank you for any and all answers! -Scott
You need Azure Active Directory. You can control everything with remote management in the way you have described. Per the provided link, "Azure Active Directory (Azure AD) provides an easy way for businesses to manage identity and access, both in the cloud and on-premises."
Double Hop Delegation: Error retrieving for user IIS APPPOOL. The underlying provider failed on Open. Login failed for user 'Domain\WebVM$'.
I'm setting up a IIS VM server to access a separate SQL Server VM, both machines running Windows Server 2016 and running on intranet. We're using windows authentication, and attemping to impersonate users through the machine account on IIS VM server machine. We are building / deploying MVC IIS bits using ASP.NET Core.
I'm hitting the above (machine account login) error after having configured everything I can think of and referred to several postings. I've configured the following main items:
Web Site setup with Windows Authentication, and ASP.NET Impersonation enabled, all other auth types disabled.
Web Site Config Editor set "system.webServer/security/authentication/windowsAuthentication" : useKernelMode to True
App Pool running .NET CLR Version "No Managed Code"
App Pool using Classic Managed Pipeline Mode
App Pool running as ApplicationPoolIdentity
Confirmed HOST SPN registered for IIS VM machine account in AD (with setspn -L IISVMServer)
Confirmed HOST SPN registered for SQL Server VM machine account in AD
Confirmed ServiceClass/Host:Port registered for SQL Server VM in AD
Registered SPN for IIS server machine account "Trust this computer for delegation to any service (Kerberos only)
Plan to lock down to constrained delegation after getting unconstrained delegation working
Tried running with / without web.config : "system.web identity impersonate="true" /system.web"
I previously posted Kerberos Double Hop Delegation with ASP.NET Core (4.5.2) which is indirectly related to this posting.

How can I RDP to an Azure box using an account I created in Azure? I don't want to go down the route of syncing directories or anything. Just simply want to be able to create accounts in Azure that can be used to access Azure servers.
This is a basic centralised authentication model and I am sure I am just missing something. Surely Microsoft can't expect us to add a bunch of users and service accounts on EACH server we create and manage passwords etc as entirely separate entities.
By "Azure Box" I assume you mean an Azure VM running Windows. There's nothing "magical" about these VMs. If you want central user management instead of relying on local user accounts you need to add it to an Active Directory domain. And if you want sync between this Active Directory domain and the Azure Active Directory for your tenant, you need to set up Directory Sync.
One cannot do this (without resorting to directory synchronisation). A Configuration Management tool such as SaltStack/Chef/Puppet seems a leaner fit than creating a traditional AD infrastructure.
In this question: ASP.NET web application unable to connect to WCF hosted as windows service
it's stated that the reason IIS could not talk to a WCF service hosted on a different machine is due to rights not assigned the app pool identity.
I'm facing the same problem I believe. What are these rights, and where do I set them?
Thanks.
This depends on the configuration of the service you're trying to access. However, if you're having trouble connecting to a different machine, you most likely don't have rights to access that computer using the machine account for the server hosting IIS. You could try adding [domain][iismachine] access to the target server (the one hosting the WCF service).
This overview has some pretty good information on what needs to be done in different scenarios.
I'm working through some WCF examples in "Windows Communication Foundation 4 Step By Step". My resulting application runs fine as long as the service is hosted in casini. It fails when I deploy the service to local IIS. When deployed to IIS, I can browse to the svc page in IE. That works.
According to the book, page 41, the app pool account needs to be a member of the db_owner role in my database. The author suggests, after verifying the correct address of the service (already did that), checking the permissions of the app pool account.
How do I verify which account is used by the application pool hosting my WCF service? Currently using the default app pool and IIS APPPOOL\DefaultAppPool is in the db_owner role. IIS APPPOOL\ASP.NET v4.0 is also in the db_owner role.
The exception is...
System.Data.SqlClient.SqlException: Login failed for user 'IIS APPPOOL\DefaultAppPool'.
How do I troubleshoot this issue? Thanks!
Solution found here:
Open IIS
double click your PC name under Connections
Click Application Pools
Select your app pool (DefaultAppPool)
Then under actions on the right click Advanced Settings,
Go to Process Model section and
click on Identity.
Now select NetworkService.
I had the same problem. Issue was that I had "IntegratedSecurity=True;" in my connection string but I was using sql authentication and passing in credentials at the same time. I removed the IntegratedSecurity piece and everything worked.
First thing you need to clear if you are using windows authentication and you are not mentioning any username password in your connection string then:
What happens when you run your code through localhost:
when you run your wcf test client from localhost, it will be able to communicate to database as local debug mode application is calling database by your account's service. So it has access to database because devenv.exe is running under your user account.
But when you deploy your web service in IIS. Now understand this service runs under IIS not under your account. So you need to assign access rights to IIS service to access the sql server for windows authentication.
Here your web service would not be able to communicate to the SQL server because of access rights issue.
So if you are using windows authentication to connect your database, you just have to change the IIS Application pool settings.
You need to change IIS Application pool's identity to local System.
Below are the Steps for windows authentication WCF:
•Open IIS (windows+R (run) then type inetmgr, then click ok)
•double click your PC name under Connections
•Click Application Pools
•Select your app pool (DefaultAppPool)
•Then under actions on the right click Advanced Settings:
•Go to Process Model section and
•click on Identity.
•Now select LocalSystem.
Now open your sql server management studio:
open run-> then type ssms then press ok
in ssms, login using your windows authentication account.
open security tab
expand logins tab
then you will be able to view your account.
Now open properties of your account
go to userMapping
then select the database you want to connect
then check the role membership services you want to use for the selected database
click ok.
add Trusted_Connection=True; property in your connection string.
Save it & deploy the web service.
Restart app pool.
you will be able to connect the database now.
if not exists
(select * from sys.server_principals where name='IIS APPPOOL\DefaultAppPool')
create login [IIS APPPOOL\DefaultAppPool] from windows;
