Azure Function App with Managed Identity scenarios to Access Azure Key Vault: 'Access Denied'
I've looked through the documentation and I'm still confused about I'm currently developing an Azure Function App that is supposed to access secrets from Azure Key Vault using a Managed Identity. However, I'm working with an 'Access Denied' behavior when trying to retrieve a secret, even though the Managed Identity has been granted the appropriate permissions. I have set up the Managed Identity for my Azure Function App and ensured that it has the 'Get' permission for secrets in the Key Vault access policies. Here's the snippet I used to configure the Key Vault: ```json { "properties": { "accessPolicies": [ { "tenantId": "<TENANT_ID>", "objectId": "<MANAGED_IDENTITY_OBJECT_ID>", "permissions": { "secrets": ["get"] } } ] } } ``` In my Azure Function, I am using the `Azure.Identity` library to authenticate and access the Key Vault: ```csharp using Azure.Identity; using Azure.Security.KeyVault.Secrets; var secretClient = new SecretClient(new Uri("https://<your-keyvault-name>.vault.azure.net/"), new DefaultAzureCredential()); try { KeyVaultSecret secret = await secretClient.GetSecretAsync("<your-secret-name>"); Console.WriteLine(secret.Value); } catch (Exception ex) { Console.WriteLine(ex.Message); } ``` When I run this code, it throws an exception with the message: 'Access denied'. I have double-checked that the Managed Identity is enabled and that the Key Vault is in the same subscription as the Function App. I've also verified that the Managed Identity is correctly displayed in the Azure portal. I've tried regenerating the access policies and re-deploying the Function App, but I still face the same scenario. Is there something I'm overlooking regarding Managed Identity or Key Vault configurations? Any guidance would be greatly appreciated! What's the best practice here?
