AADSTS50020: User account '{EmailHidden}' from identity provider does not exist in tenant 'Microsoft Services' and cannot access the application - azure-keyvault

Question

Using Azure.Identity Running dotnet 6.0.302 On Windows 10 Visual Studio 2022 v17.1.5 App Type - Asp.Net Core Web Api
I am trying to implement Azure App Configuration.
While using DefaultCredentials() the attempt to obtain an authentication token fails at all levels of credential types. I tried providing a user assigned managed identity but no avail.
I notice something fishy in the logs though. there are instances of Azure.RequestFailedException: A socket operation was attempted to an unreachable network. (169.254.169.254:80) but i am not sure what the ip address refers to.
Please Note:-
I could not ping this ip address from my PC.
The error is same irrespective of using a Managed Identity. So using just new DefaultAzureCredential() without any parameters also throws the same error.
I am using my personal Azure Subscription.
Kindly provide guidance to solve this issue and move forward.
Here is my WebApi configuration
var builder = WebApplication.CreateBuilder(args);
// Setup a listener to monitor logged events.
using AzureEventSourceListener listener = AzureEventSourceListener.CreateConsoleLogger();
var defaultClientCredentialsOptions = new DefaultAzureCredentialOptions()
{
Diagnostics =
{
LoggedHeaderNames = { "x-ms-request-id" },
LoggedQueryParameters = { "api-version" },
IsLoggingContentEnabled = true
}
};
// Plugin App Configuration Store
var appConfigStore = builder.Configuration.GetConnectionString("EshopClone:AppConfiguration");
var userAssignedMIClientId = builder.Configuration["UserAssignedMIClientId"];
var credential = new DefaultAzureCredential(new DefaultAzureCredentialOptions { ManagedIdentityClientId = userAssignedMIClientId });
builder.Host.ConfigureAppConfiguration(hostBuilder =>
{
hostBuilder.AddAzureAppConfiguration(options =>
{
options.Connect(appConfigStore)
.ConfigureKeyVault(kv =>
{
kv.SetCredential(credential);
});
});
});
Here is the detailed error:

Answer 1

All the exceptions including RequestFailedExcpetion ,AADSTS50020 (which are often caused by the DefaultAzureCredential authenticating an account other than the intended one or when that account does not have the correct permissions or roles assigned.) etc leads to saying User being Unauthorized to call that particular endpoint where your target might be on a different network for that endpoint which is leading to socket exception .
Please check following ways that can resolve the issue.
Sign out and sign in VS again. select Tools > Options menu to launch the Options dialog In Visual Studio.
Navigate to the Azure Service Authentication options and sign in with your Azure Active Directory required account.
To try and get the right account to access, try using AzureCli, loggin
into that one account and sign out of your others or with VS, make
sure that the tokens are only being requested from that one account
and not any other
use the below cli command account to verify the account which is
currently logged in but before that please ensure the Azure CLI is
properly installed. Installation instructions can be found here.
az account show
Once you've verified the Azure CLI is using correct account, you can
validate that it’s able to obtain tokens for this account.
az account get-access-token --output json --resource https://management.core.windows.net
Update Visual Studio and packages to the latest version.
excluding the credential with the ExcludeXXXCredential property
Please Note that credentials such as the
InteractiveBrowserCredential are not included by default which
requires user interaction. You may have to enable or disable
required credentials this when constructing the
DefaultAzureCredential by setting for example:the
includeInteractiveCredentials to true, or the
ExcludeInteractiveBrowserCredential property to false in
DefaultAzureCredentialOptions.
Try by giving ExcludeVisualStudioCredential to true if above steps
doesnt resolve the issue .Or you can include azurecli credential or
others to for user authentication .
var options = new DefaultAzureCredentialOptions()
{
ExcludeAzurePowerShellCredential = true,
ExcludeEnvironmentCredential = true,
ExcludeAzureCliCredential = true,
ExcludeInteractiveBrowserCredential = false,
ExcludeManagedIdentityCredential = true,
ExcludeSharedTokenCacheCredential = true,
ExcludeVisualStudioCodeCredential = true,
ExcludeVisualStudioCredential = false
};
var cred = new DefaultAzureCredential(options);
Please ensure that the correct role is assigned to the account being
used specific to that service rather than overall subscription role
such as owner for subscription
Ensure that relevant environment variables are set prior to
application
• To authenticate a service principal which is using a
client secret, ensure the variables AZURE_CLIENT_ID, AZURE_TENANT_ID and AZURE_CLIENT_SECRET are properly set .
• And
for managed identity for App Service make sure it is configured
properly and environment variables like MSI_ENDPOINT and
MSI_SECRET have been set in the environment. Instructions can be
found here.

Answer 2

Your code uses a connection string to connect to Azure App Configuration and uses AAD (user-assigned managed identity) to connect to Key Vault (for Key Vault references). The problem is not with Azure App Configuration but with the Key Vault. Please make sure you granted your user-assigned managed identity the read permission to the secrets in your Key Vault.
Please check out the Grant your app access to Key Vault in the doc below:
https://learn.microsoft.com/azure/azure-app-configuration/use-key-vault-references-dotnet-core?tabs=core5x#grant-your-app-access-to-key-vault

Answer 3

You need to provide the correct TenantId for Visual Studio authentication:
new DefaultAzureCredential(new DefaultAzureCredentialOptions { VisualStudioTenantId = "<your_tenant_id>" })
The related part of your error log is:
Process "C:\Program Files\Microsoft Visual Studio\2022\Community\Common7\IDE\CommonExtensions\Microsoft\Asal\TokenService\Microsoft.Asal.TokenService.exe" has failed with unexpected error: TS003: Error, TS004: Unable to get access token. 'AADSTS50020: User account '{EmailHidden}' from identity provider 'live.com' does not exist in tenant 'Microsoft Services' and cannot access the application '872cd9fa-d31f-45e0-9eab-6e460a02d1f1'(Visual Studio) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account.
