My web app tries to use ManagedIdentityCredential on local development computer #21075

JandosHk · 2021-05-14T05:51:16Z

In ASP.NET Core 3.1 web app, I' m using Azure key vault configuration:

	public static IHostBuilder CreateHostBuilder(string[] args)
	{
		return Host.CreateDefaultBuilder(args)
			.ConfigureAppConfiguration((context, builder) =>
			{
				var secretClient = new SecretClient(
					new Uri("https://MyKeyVault.vault.azure.net/"),
					new DefaultAzureCredential());
				builder.AddAzureKeyVault(secretClient, new KeyVaultSecretManager());
			})
			.ConfigureWebHostDefaults(webBuilder =>
			{
				webBuilder.UseStartup<Startup>();
			});
	}

Azure.Identity v1.2.3 is installed transitively, when I installed Microsoft.Identity.Web v1.8.2.

It works on my local development computer, when I run my web app from within Visual Studio 2019, by pressing F5 (debug mode). I checked; the actual credential used was SharedTokenCacheCredential (by replacing DefaultAzureCredential with EnvironmentCredential, ManagedIdentityCredential, and SharedTokenCacheCredential in that order).

Now, in my new computer I installed Visual Studio 2019, git cloned my web app, and ran the web app.
The web app threw an exception: AuthenticationFailedException: ManagedIdentityCredential authentication failed: Retry failed after 4 tries.

Looks like, the web app is trying to use ManagedIdentityCredential in my local development computer (If I replace DefaultAzureCredential with SharedTokenCacheCredential, then it works in my new computer). Why is it happening?

Hi @JandosHk
Would you mind providing the logging output after reproducing this with logging enabled?

Hi @christothes

I tried logging today, but it seems that after using SharedTokenCacheCredential or VisualStudioCredential, the error has gone.
Below is what I got when the error was thrown before I tried other credential types:

An error occurred while starting the application.

christothes · 2021-05-17T14:20:18Z

Does this still reproduce wit the latest version of Microsoft.Identity.Web (which uses version 1.3.0 of Azure.Identity) or after directly taking a dependency on the latest Azure.Identity 1.4.0?

JandosHk · 2021-05-18T07:53:57Z

Today I installed Microsoft.Web.Identity 1.10.0 (which uses Azure.Identity 1.3.0). and the same error was thrown. Directly installing Azure.Identity 1.4.0 didn't help either.

christothes · 2021-05-18T15:16:27Z

Thank you for trying the newer version.
Would you mind providing the logging output after reproducing this with logging enabled?

JandosHk · 2021-05-19T00:55:29Z

I enabled logging like below:

public static IHostBuilder CreateHostBuilder(string[] args)
{
    return Host.CreateDefaultBuilder(args)
        .ConfigureAppConfiguration((context, builder) =>
        {
            using AzureEventSourceListener listener = AzureEventSourceListener.CreateConsoleLogger();
            SecretClientOptions options = new SecretClientOptions()
            {
                Diagnostics =
                {
                    IsLoggingContentEnabled = true
                }
            };

            var secretClient = new SecretClient(
                new Uri("https://MyKeyVault.vault.azure.net/"),
                new DefaultAzureCredential(),
                options);
            builder.AddAzureKeyVault(secretClient, new KeyVaultSecretManager());
        })
        .ConfigureWebHostDefaults(webBuilder =>
        {
            webBuilder.UseStartup<Startup>();
        });
}

Is it correct? I couldn't find any example where listener variable is used.

What I get on my VS2019 output window is below:

        {
            webBuilder.UseStartup<Startup>();
        });
}

Is it correct? I couldn't find any example where listener variable is used.

Almost - you want to set the logging options on the DefaultAzureCredentialOptions.

I suspect that the logging will show that you have some device on the local network responding on the IP address 69.254.169.254

JandosHk · 2021-05-28T06:07:04Z

I set logging like below:

DefaultAzureCredentialOptions opts = new DefaultAzureCredentialOptions
{
	Diagnostics =
	{
		IsLoggingContentEnabled = true
	}
};
var secretClient = new SecretClient(
	new Uri("https://MyKeyVault.vault.azure.net/"),
	new DefaultAzureCredential(opts));
builder.AddAzureKeyVault(secretClient, new KeyVaultSecretManager());

Logging messages are below:

BTW, do you mean 169.254.169.254?

christothes · 2021-06-04T14:13:45Z

I set logging like below:

DefaultAzureCredentialOptions opts = new DefaultAzureCredentialOptions
{
	Diagnostics =
	{
		IsLoggingContentEnabled = true
	}
};
var secretClient = new SecretClient(
	new Uri("https://MyKeyVault.vault.azure.net/"),
	new DefaultAzureCredential(opts));
builder.AddAzureKeyVault(secretClient, new KeyVaultSecretManager());

BTW, do you mean 169.254.169.254?

Yes, I meant to say that IP address.

I think we may be missing one more step on the logging. Can you try adding the following?

// Setup a listener to monitor logged events.
using AzureEventSourceListener listener = AzureEventSourceListener.CreateConsoleLogger();

JandosHk · 2021-06-08T00:10:39Z

@christothes, I did it again and got the same log messages. The problem is I don't understand where that listener is referenced in the code? Just initializing it doesn't make a sense to me.

christothes · 2021-06-11T20:29:35Z

Could you run the following PowerShell command? It will reveal which process is listening on the ip address

Get-Process -Id (Get-NetTCPConnection -IPAddress 169.254.169.254).OwningProcess

JandosHk · 2021-06-14T07:11:20Z

@christothes, somehow the error on my PC disappeared, but my coworker still facing the issue. On her computer, when she executed the command, the following error was thrown:

No MSFT_NetTCPConnection objects found with property 'RemoteAddress' equal to '169.254.169.254'. Verify the
value of the property and retry.

Then, she started our web app in debug mode (from VS2019 pressed F5), and executed the command again. This time she got the following:

Handles NPM(K) PM(K) WS(K) CPU(s) Id SI ProcessName
866 81 77804 68504 0.91 20752 2 iisexpress

Do you see something wrong in here?

JandosHk · 2021-06-14T07:31:26Z

@christothes, BTW, in my PC, even after I started my web app, the command throws the error given above (and the web app works fine).

christothes · 2021-06-14T14:20:45Z

I'm not sure why iisexpress would be using 169.254.169.254, but this is definitely the source of the problem. As a workaround for local development, you could add the following DefaultAzureCredentialOptions

var options = new DefaultAzureCredentialOptions { ExcludeManagedIdentityCredential = true };
