One of our app services has a system assigned identity:
We wanted to start using Azure keyvault and use this identity to give this app service access.
Unfortuntatly the identity cannot be found:
Did anybody had a similar problem before?
I tried to find the system assigned identity in other places like Azure Ad but it could not be found there either.
I tried using systen assigned identities for other app services we have and it worked for those. So the problem is only present for that specific one.
I tried to reproduce the same in my environment and got the results successfully as below:
I created an Azure App Service and turned-on System Managed Identity:
Copy the Object ID and you will find the application in Azure Enterprise Applications as below:
Now, I created an Azure Key Vault and created access policy:
Search with the ObjectID of the Application as below:
The access policy created successfully using Service Principal as below:

I am writing a script that logins into Azure, but I don't want to use my password explicitly. Therefore I switched on a system assigned managed identity:
And now in a shell script I do this:
az login --identity --username xxx
'xxx' is the Object (principal) ID, on the screenshot
when I execute the command, I get this (replaced ip and ID with 'xxx'):

EDIT: it is fine, when I run this command in Cloud-Shell on Azure portal.
Why can't I login? Am I missing something?
A system assigned managed identity cannot be used to login. It is explicitly tied to the service you created it for, and is not meant for re-use.
System-assigned. Some Azure services allow you to enable a managed identity directly on a service instance. When you enable a system-assigned managed identity, an identity is created in Azure AD. The identity is tied to the lifecycle of that service instance. When the resource is deleted, Azure automatically deletes the identity for you. By design, only that Azure resource can use this identity to request tokens from Azure AD.
The most important part of that quote is the last sentence:
By design, only that Azure resource can use this identity to request tokens from Azure AD.
More information: What are managed identities for Azure resources?.
Also:
Can’t be shared.
It can only be associated with a single Azure resource.
EDIT:
Based on your question and the comment below you might be looking for a Service Principal. A managed identity, either system assigned or user assigned, is for use with an Azure resource.
Managed identities provide an identity for applications to use when connecting to resources that support Azure AD authentication.
An Azure service principal is an identity created for use with applications, hosted services, and automated tools to access Azure resources.
For more information on Service principals, see Create an Azure service principal with the Azure CLI.
I have a SSL cert in my Azure key vault that I am trying to import to the correct App Service.
I am the owner of the Azure subscription and I have given the App Service GET and LIST permissions for certificates on the vault.
On my App Service I click TLS/SSL settings > Private Key Certificates (.pfx) > Import Key Vault Certificate
This is the message I receive
Another owner on the subscription is able to complete this process successfully. So I am not sure why I am not able to when we both have owner roles on the subscription?
Is anyone able to offer any suggestions please?
When you are trying the operation from Azure Portal and you are a Owner of the Subscription, then Azure by default adds a access policy for the Azure APP Service Resource Provider and you do not further require to add the any access policies for the Web App.
Example:
I created a Web App with system managed identity and a Key vault with the below added Access Policies. I am an Owner of the Subscription and a User in the Azure Active Directory.
When , I perform the import certificate operation in the TLS/SSL Settings, the access policy get automatically updated with the Azure App Service Service Principal Credential.
In your case its not able to find the details of the Resource Provider Service Principal. As a Solution you can try adding Microsoft.Azure.CertificateRegistration (i.e. ObjectId : ed47c2a1-bd23-4341-b39c-f4fd69138dd3) , Microsoft Azure App Service (Internal) (i.e. ObjectId : 505e3754-d8a9-4f8b-97b6-c3e48ac7a543) & Microsoft Azure App Service (i.e. ObjectId : f8daea97-62e7-4026-becf-13c2ea98e8b4) in access policy for key vault.
Note: If the Issue is still not resolved , Please reach out to Azure Support for better assistance.
I have created a asp.net API that accesses KeyVault to get secrets.
When I run locally on my laptop, I use Managed Identity to access KeyVault with a dedicated Service Princiapl. (with AZURE_CLIENT_ID, AZURE_CLIENT_SECRET and AZURE_TENANT_ID set in my system
environment variables).
This is working just fine.
Now I have created a VM in Azure to be used as a developer machine. All the tools are installed and configured like they are on my laptop.
But when I run the web API I get a 403 telling me the object ID #### does not have Get/List access to KeyVault.
I've checked and the object ID matches the one of the VM. Indeed the VM does not have this access to KeyVault, however I'd expect the Web API to run with the configured AZURE_CLIENT_ID in my environment variables.
Am I missing something ?
Ensure get/list operations are selected/enabled in the access policy created for your managed identity/service principal:
I am trying to link Azure Key Vault secrets to a variable group in Azure Pipelines (part in Azure DevOps). Microsoft documentation here.
However, the "Authorize" button does not seem to work. It spins endlessly. Screenshot.
My target Azure Key Vault already has the service principal included in its access policy with Get and List permissions. Screenshot.
Anyone seen this issue before?
This workaround also seems like a bug for Azure Key Vault deployments using ARM templates.
If the service principal in question is added to the Azure Key Vault (AKV) access policies through an ARM template by referencing the service principal's Object ID (as Microsoft documentation calls for), permission errors with Azure Pipelines follow.
However, if I manually add the service principal to the AKV's access policies by referencing the service principal's application (client) ID, the permissions errors go away entirely.
Again, feels like a bug. And now my automated deployment pipeline doesn't quite work because of this manual step.
Also, in the AKV ARM template, if I were to combine the mandatory field objectId with the optional field applicationId, the service principal shows up as a "compound identity". That does not fix the permissions issues in Azure Pipelines. I do not see a way of adding a service principal properly without doing it manually.
Firstly, please make sure the service connection is working correctly. Then refresh the page and try it again. Alternately you can also try in browser inprivate session.
Just as the message said "The specified Azure service connection needs to have "Get, List" secret management permissions on the selected key vault."
Basically, we need to click the "Authorize" button to enable Azure Pipelines to set these permissions for the specific service connection.
If that doesn't work, we can also manually set the permissions for the specific service connection.
Go to Project settings - > Service connections -> Select the
specific ARM service connection
Click Edit to popup the Update Authentication for xxx dialog
Click the "use the full version of the service connection dialog."
link, to get the Service principal client ID
Go to your key vault in Azure portal -> Access Policies -> Add a new
Access Policy -> Select a template (e.g Key&Secret Management) - >
Select Get, List for Secret permissions.
Click Select Principal -> Copy and paste the Service principal client ID
to search the user/application -> Select the searched
user/application
After that you can see the new APPLICATION access policy.
Try it again after successfully adding the application access policy.
UPDATE:
Generally in Azure DevOps we need to create a ARM service connection (the client which can access the azure sources) first before deploying an Azure Key Vault through an ARM template.
Actually when you select the Azure subscription then click Authorize in Azure resource group deployment task
, the ARM service connection is created automatically. You just need to check the AppID and get the ObjectID to use in the ARM template.
We can get the Service principal client ID (AppID) by following above steps. After that we can get ObjectId by the AppID with running the following command: (See Find service principal object ID using PowerShell for details.)
$(Get-AzureADServicePrincipal -Filter "AppId eq 'a89c3dee-f5bf-4ea1-a805-d4c729a4add3'").ObjectId
Then you can specific the ObjectId when deploying the Azure Key Vault through an ARM template.
I am trying to import a certificate from a Key Vault to an App Service to configure SSL in the Azure Government Cloud. When I do this I get an error stating:
Failed to get App Service Service principal details.
I am getting a similar error when I try to do this through an ARM template which it what caused me to try this manually. I have tried giving my App Service a managed identity and giving that identity access to the key vault. I have tried a technique that worked in the regular Azure Cloud of giving "Microsoft Azure App Service" account permission to the key vault but that doesn't seem to exist in the Government Cloud.
I would have expected this to simply work and allow me to configure my SSL correctly on the app service so I don't need to manage the certificates individually on every app service.
You have to enable in the Identity of your app services that can be assigned through the azure permissions, then you have to go to the KeyVault and grant the permissions to the App Services.

I eventually found the solution to the issue.
Following the directions found here:
https://github.com/Azure/azure-quickstart-templates/tree/master/201-web-app-certificate-from-key-vault
I tried to authorize the 'Microsoft.Azure.WebSites' Resource Provider as described in the link, but that GUID doesn't exist in the Government Cloud.
This link however does give you the equivalent GUID for the Government Cloud:
https://github.com/MicrosoftDocs/azure-docs/blob/master/articles/azure-government/documentation-government-services-webandmobile.md#app-services
After using the script from the first link with the GUID value from the second link I was able to get both deployments and manual SSL added.
