Unable to connect to Azure US Gov Cloud when migrating an Access database - " This is not supported - the app and the request must target the same cloud. "

[JordanPavlic]

I get the following when I attempt to connect to an instance of Azure SQL Server on the Azure US Gov Cloud using Azure Active Directory - Interactive with MFA:

Connection to Azure SQL Database failed. You did not define an authority at the application level, so it defaults to the https://login.microsoftonline.com/common. However, the request is for a different cloud login.microsoftonline.us. This is not supported - the app and the request must target the same cloud.

Add .WithAuthority("https://login.microsoftonline.us/common") in the app builder. See https://aka.ms/msal-net-authority-override for details

I've searched the web and tried Chatgpt, but I've been unable to find a way to resolve this.

Here's what Chatgpt said about this:

The error you're encountering suggests that the authority URL for Azure Active Directory (AAD) authentication isn't set correctly in your application, causing a mismatch between the authority specified in your app and the one being requested. You need to ensure that the authority URL in your application matches the Azure cloud environment you are targeting.

Here's how you can modify your application to specify the correct authority URL:

Update your application code to specify the authority URL: Locate where you are configuring the MSAL (Microsoft Authentication Library) client and add the .WithAuthority method to set the correct authority.

In C#, it might look something like this:

var clientApp = ConfidentialClientApplicationBuilder.Create(clientId)
                    .WithClientSecret(clientSecret)
                    .WithAuthority("https://login.microsoftonline.us/common")
                    .Build();

Ensure your configuration matches: If you have your configuration settings in an appsettings.json or similar configuration file, make sure the authority URL is set correctly there as well.

For example, in appsettings.json:

{
    "AzureAd": {
        "Instance": "https://login.microsoftonline.us/",
        "TenantId": "your-tenant-id",
        "ClientId": "your-client-id",
        "ClientSecret": "your-client-secret"
    }
}

Review your code for any hardcoded values: Ensure that there are no hardcoded authority URLs elsewhere in your code that might be causing the mismatch.

Check the environment you are targeting: Confirm that you are indeed supposed to use the login.microsoftonline.us authority. This is typically used for US government cloud environments. If you are using the public cloud, the correct authority is usually login.microsoftonline.com.

Here is an example of how you can initialize the MSAL client correctly:

using Microsoft.Identity.Client;

// Create the confidential client application
var clientApp = ConfidentialClientApplicationBuilder.Create("your-client-id")
    .WithClientSecret("your-client-secret")
    .WithAuthority(new Uri("https://login.microsoftonline.us/common"))
    .Build();
// Use the clientApp instance to acquire tokens

By ensuring that the authority URL in your configuration and code matches the intended Azure environment, you should be able to resolve this issue. If you need further details or examples, the documentation at the provided link https://aka.ms/msal-net-authority-override can be very helpful.

I haven't found any way to configure this through the gui of the SSMA application so I'm stuck on this. My guess is this is a bug in the SSMA application where it assumes the user is connecting to the public azure cloud and uses the auth endpoint (https://login.microsoftonline.com/common) for that cloud. The edge case this misses is the azure gov cloud uses a different auth endpoint (https://login.microsoftonline.us/common).

Any help with this is greatly appreciated,
