[BUG]Azure.Identity 1.13 Breaks DefaultAzureCredential On DevBox

[keggster101020]

Library name and version

Azure.Identity 1.13

Describe the bug

My code is using DefaultAzureCredential(true) to authenticate to remote azure resources. After upgrading Azure.Identity to 1.13 a handful of users are noting that they are getting the following error when running inside of Microsoft DevBox:

'ManagedIdentityCredential authentication failed: [Managed Identity] Authentication unavailable. Either the requested identity has not been assigned to this resource, or other errors could be present

There are no assigned identities to these DevBoxes (we are using the devbox.microsoft.com instances not selfhosted). Downgrading to 1.12 seems to have resolved this issue but putting this bug here as it seems like the detection logic around DefaultAzureCredential may be incorrect in 1.13.

I was under the impression that DefaultAzureCredential was a chained credential and that any failures in the chain would only be thrown back to the user if none of the credentials in the chain succeeded. However, the interactive popup never showed up, also some users have the VSCredential and the MI credential error happens seemingly as soon as it fails.

Expected behavior

Using DefaultAzureCredential(true) inside a DevBox VM with no managed identity would attempt other credentials in the chain before throwing an exception back to the user.

Actual behavior

DefaultAzureCredential(true) throws an exception on DevBoxes if there is no MSI attached to the devbox and doesn't attempt any further credential operations.

Reproduction Steps

1. Create a DevBox at (https://devbox.microsoft.com/)
2. Create a c# project with Azure.Identity 1.13
3. Make a call to new DefaultAzureCredential(true).GetTokenAsync(<some token request context>)
4. Observe the ManagedIdentity exception

Environment

Microsoft Devbox (https://devbox.microsoft.com/)

We're also running into this error running on our DevBox. We're using the Azure.Identity in combination with the Microsoft.Configuration.ConfigurationBuilders.AzureKeyVaultConfigBuilder class. Using version Azure.Identity 1.12 there were no problems. Upgrading to 1.13 gives the following error:

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Thanks for reporting - I am investigating.

Hi @keggster101020
I am unable to reproduce this. Could you try creating the credential the following way to see if you still do not get prompted for interactive credentials?

Also, could you enable logging and share that with me for the failure scenario? For console output, you would just need to add the following line to your program.

using AzureEventSourceListener listener = AzureEventSourceListener.CreateTraceLogger();

If you need to log the output somewhere other than the console, this is described in these docs.

            var options = new DefaultAzureCredentialOptions
            {
                ExcludeEnvironmentCredential = true,
                ExcludeWorkloadIdentityCredential = false,
                ExcludeManagedIdentityCredential = false,
                ExcludeAzureDeveloperCliCredential = true,
                ExcludeSharedTokenCacheCredential = true,
                ExcludeVisualStudioCredential = true,
                ExcludeVisualStudioCodeCredential = true,
                ExcludeAzureCliCredential = true,
                ExcludeAzurePowerShellCredential = true,
                ExcludeInteractiveBrowserCredential = false
            };
            var cred = new DefaultAzureCredential(options);
