Microsoft Fabric connect to Azure Key Vault

[datakohai12]

Greetings everyone, 

I am trying to establish a connection between my Microsoft Fabric notebook and an Azure KeyVault to access some secrets. Unfortunately, I am facing an issue with MSI while using Power BI, as it keeps timing out when trying to obtain a token. Any suggestions on how to resolve this issue would be greatly appreciated. Thank you.

@datakohai12  Thanks for sharing the steps Fabric currently does not support managed identity authentication which is what this is trying to authenticate via.  Until that's fully integrated, there's a simple workaround.  As long as you are executing notebook has access to the vault, the below will work.  

from trident_token_library_wrapper import PyTridentTokenLibrary as tl

access_token = mssparkutils.credentials.getToken("keyvault")

tl.get_secret_with_token("https://vaultName.vault.azure.net/","secretName",access_token)

@datakohai12 It wouldn't be present in pypi

you should be able to execute that code directly in your Trident notebook if you're not able to send over a screenshot of the error.

Yes, I'm have access to the fabric in it's tenant and the key vault in another tenant.

This is the error I received:

I'm get the same invalid issuer notebook and am using the PyTridentTokenLibrary but the notebook and KeyVault are in different tenants. Is there a workaround for this ? Or is the managed identity method available now?

@ritikesh managed identity authentication is till not available. do you have access to the KeyVault with your account? could you please share the snapshot of the code/error?

Hi!  How do we give the executing notebook as access to the key vault?

[Jaimini]

Hi @blhart216beazer 

As long as you are using the same account for running the notebook and having access to KeyVault with the same account, you can extract secret from KeyVault and use them in notebook.

I have used the above code to mount the data lake gen2 using notebook in microsoft fabric and getting below error - An error occurred while calling o4394.getSecretWithToken. : java.io.IOException: 401 {"error":{"code":"Unauthorized","message":"AKV10032: Invalid issuer.

Hi Geetha,

I apologize for the delayed response. Thanks for the workaround; I am using it now, though I am having trouble finding trident_token_library_wrapper. Could you direct me to it in PyPi?

Hi,

The following are my steps:

1. Created a Synapse Data Engineering Notebook
2. Granted the Power BI Service Account Get permissions via Access Policy in the Azure Key Vault

Here is a screenshot of the code and the error message:
