Hi @kannangce Don't understand your question. What's ApplicationTokenCredentials you are referring to?

[kannangce]

@XiaoningLiu My existing code uses authfile based authentication with Azure. For testing , local setup if I have to make a drop-in-replacement of Azurite, I'll be needing one of the below things,

• An auth file containing the credentials.

• Java SDK's ApplicationTokenCredentials instance which in turn is created from the auth file, which requires confgurations like ClientId, Client Secret, TenantId and Subsription Id.The mentioned parameters for Azurite is not mentioned in the readme.

If one of the above is possible with Azurite that would be awesome to integrate Azurite in my case.

Hi @kannangce

It should work. If the token credential works for your production storage account, then it will work for Azurite. Anyway take a try, report any Azurite errors/debug.log here.

I am also wanting this information. We want to run this in a testing pipeline, however, we will not be injecting production secrets into there for testing purposes....

@XiaoningLiu Specifically:

When using a ClientSecretCredential, which requires a ClientId, TenantId, and a Client Secret, what does this library expect...?

What does azurite expect for the ClientId, TenantId, and Client Secret. Putting fake values in there does not work, and there is no mention in the readme of what is expected here, nor is there a runnable example.

Guess you are using TokenCredential or similar SDK, which requires you input valid ClientId, TenantId etc. Unluckily the SDK cannot support granting a fake token to Azurite. The SDK will go to AAD asking for a production token.

There are 2 ways you can explorer:

1. Go to your Azure portal creating an application just for Azurite tests. You can decouple the credentials with your production services. The input ClientId, TenantId using the newly created application credentials.

2. You can build up code by-yourself to fake tokens to Azurite. Refer to https://github.com/Azure/Azurite/blob/24533376c9bb11ceef005eac5242738032f7196d/tests/blob/oauth.test.ts#L30 and https://github.com/Azure/Azurite/blob/24533376c9bb11ceef005eac5242738032f7196d/tests/testutils.ts#L179
