I've got a VM running Windows 10 somewhere (with internet access). It is hooked up to Azure AD, and I can sign in with my domain credentials. Now I need to run a service as another user in Azure AD (it's actually a service account) since it's got all the correct permissions.
When I try to set it naively, I get an error about which says (approximately) that the domain is not in my list of locations.
Is there any way for me to do this?

I'm investigating a failure in my Windows 10 Credential Provider. It calls out to LookupAccountName in order to get the SID of the user that is attempting to log in. Its per-user configuration uses the account SID as the key.
The failure scenario is as follows:
There is a mixture of local and domain accounts on a domain joined computer.
The computer is in an offline or otherwise disconnected state and cannot contact the domain controller.
The domain user has logged in to this computer in the past and its credential is cached.
The call to LookupAccountName fails with ERROR_TRUSTED_RELATIONSHIP_FAILURE (0x6FD)
Here's where things are interesting:
I can log in with a local account and then "Run As" the domain user. Then subsequent calls to LookupAccountName (even when run in the context of the local user) succeeds in looking up the SID of the domain user. It will continue to work until the computer is rebooted.
I've tried calling LookupAccountName as well as LsaLookupNames2. Both exhibit the same behavior. (I assume LookupAccountName is built off of LsaLookupNames2).
It doesn't look like the NetUser* APIs will help me, as I believe they are intended for local accounts.
Is there a way to lookup the account SID for an offline domain credential? Without requiring them to log in first?
Why does using "Run As" cause these APIs to suddenly work?
I work in a team that uses Azure Service Fabric and I want to connect to an Azure SQL database using my Azure AD account instead of using a SQL username/password when running locally.
Service Fabric runs locally on a cluster and runs as the NT Authority\Network Service user. I believe that it's possible to change the user that it runs under, but when I tried it seemed to remove the ability to use Visual Studio to debug the app. It also required having the password in the config which is not ideal.
I'm trying to login to Azure AD with the AzureCli and the az login command and can do this easily with my local user azuread\chester.
A comment on github suggests that I should be able to run a powershell prompt as the network service and use az login to login with my account. When I tried this it failed with a generic error:
Does anyone know if it's possible to login to AzureAD with the NT Authority\Network Service user?
I know it's possible to use an Azure App Registration as a principal, but this method still involves a password and i'm trying to avoid passwords.
It is perfectly possible but, since it's a non-interactive account, the optimal choice is to login as an application. This, however, implies high level permissions so careful attention must be paid when consenting them. Also, it's possible to login as a user using the ROPC flow, however this one is not recommended due security and technical limitations.
Regarding az cli take a look at Sign in with a service principal.
I was installing the filebeat application and I noticed that I needed to run powershell as administrator in order to install them. When I checked the service using wmic service get name,startname,status it showed Local System. I'm wondering what this account is as this is neither the user account or the administrator account. Will this always be the case when I install services as administrator? What is the difference if I install it as a normal user and as administrator?
In any case, I've set this service to start automatically when windows start. Would this service start only when the user I used to install it logs in or will it start regardless of which user logs in?
OK, let's unpack that one by one, in no particular order:
Only a user with administrator rights can install a service.
Services that are configured to start automatically are started as soon as Windows is up and running; Windows does not wait until somebody logs in. It makes no difference to the service who the logged-on user is, or whether anybody is logged in at all, unless the service application itself has been explicitly programmed to check.
The program that installs the service decides what account the service uses to run. Windows doesn't care what user account was used to install the service, it doesn't even keep track.
If the program that installs the service wants it to use an ordinary user account, it must know the password for that account. There are various special accounts that a service can run in, these accounts do not require a password. One of these special accounts is Local System.
Local System is the highest-privilege service account in Windows; it has all the same rights as an administrator, and can do things an administrator can't. Local System is also the account that the user-mode part of Windows itself runs in, roughly equivalent to the UNIX root account except that it doesn't have a password.
Additional notes, for completeness:
One alternative to Local System is for the service to run as Local Service or as Network Service, which are non-administrative service accounts. The only difference between the two is that if the computer is joined to an Active Directory domain, the Network Service account has network access to other machines in the domain and the Local Service account does not.
It is also possible to configure a service to run in a special service account that is unique to that particular service. This is mostly useful if you want the service to have access to a particular file or folder, but do not want to give it administrator rights.
Nitpickers corner:
It is I believe technically possible to reconfigure Windows to allow non-administrators to install services, but this is not supported and would be a Very Bad Idea. If you did, though, it would still make no difference who installed the service. Windows doesn't record this information.
Hopefully a simple one.
If I run powershell on my XP machine and run:
PS> get-childitem \\networkdrive\$share\folder\file.ext
the command successfully completes and returns the information I am looking for.
If I run the same command from team city it error with an Object-Not-Found. (The team city server and agent are running on the same machine that succeeds with the command)
I'm presuming that this is because Windows Services (what the agent is running as) cannot access network drives.
Does anyone have a simple workaround for this?
The problem is not that team city is running as an Windows Service. The problem is that the account used for that service do not have access to the network share.
There are two solutions to the problem:
1) Change the account of the service to an account which have access to the network share.
Open Services-> Find the team city services
Right click-> Properties -> Go to the Log On tab
Put in the name and password of an account with access
2) Grant the currently used account (most likely the Network Service Account) access to the share.
Use the above steps to figure out which account Team City is running under
On the share Grant access to that account
If it is the Network Service or System account, you need to add the Computer as an account instead of a user. So make sure you pick Computer as object type in the Add dialog.
How can I configure Visual Studio remote debugging when:
My developer machine is a member of an AD domain, and my username is "DevelopersName".
The "remote" machine is on the same Ethernet segment, but is not part of the domain.
The "remote" machine must run software under "RemoteUserName".
Most documentation I can find suggests that you need have both machines in the same domain and with identical usernames. That's not possible here.
I could possibly add my username to "remote", but the software still needs to run under "RemoteUserName.
If it helps, I could add 2nd network card to my developer machine and directly connect the "remote" machine.
Using VS2008, but will be moving soon to VS2010.
Thank you.
Sorry, but I've just spent the last 10 hours trying to debug your exact problem. My findings are not good.
You need to get your accounts synced, especially if you are using your remote app to connect to other systems in your SOA environment, ie: Sharepoint, AD.
You can to some extent get remote debugging to work, if you create an account on your local machine with the same name as that of your remote machine (lets do it like this rather rather than working with the domain account).
You then need to make sure the remote service is running under this account, and its a member of the administrators group. And by this I mean hold down control, and right click run as - with the remote debugger, and select the user (not required if remote server is logged in as the required user).
Run the wizard it will open the required ports, use Authentication, because non authentication won't debug managed code. Breakpoints are never met, and there is nothing you can do about this.
On your local dev machine, log off your domain account, and log onto the local account with matching name as the account on server thats running the remote service.
Now you stand a change of remote debugging. If you can't do any of the above, sorry there is no workaround, its entirely dependent on the user account and having the right permissions.
If you don't want to create a local account, try starting our debugger via command prompt using the following command:
runas /user:[user#machinename] /netonly [debugger.exe]
E.g.:
runas /user:john#mypc123 /netonly devenv.exe
I assume it's managed debugging you're talking about (for native debugging there's a remote debugging solution with no authentication). In this case, I would suggest that you use a local user to launch the debugger on your machine. If this local user's name and password match "RemoteUserName"'s name and password, it should work.
(Note that this does not preclude you from using the AD account to log in to your workstation, you just need to set up another account and use runas to launch Visual Studio.)
