stored the connection string in azure key vault. I added the access policy that azure purview can access the azure key vault.
My connection string is :
Server=tcp:imagevalidation.database.windows.net,1433;Initial Catalog=Imagevalidator;Persist Security Info=False;User ID=sqllogin;Password=xxxxxxxx;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;
The same connection string works fine in azure data factory. I can authenticate that database using azure key vault.

So how we can fetch the secrets or keys for Azure Data Factory , logic apps, Azure Synapse and Azure DataBricks if we disable the public access for keyvault.
I found a solution for AppServices and FunctionApps by using outbound IP Addresses and i need a solution for accessing the ADF,synapse,logicapps and databricks if we disable public access for keyvault.
I tried using Service Principal and grant permissions but its not working.
Please help me with the solution.
Even if you disable public access, you can still leave "Allow trusted Microsoft services to bypass this firewall" on, and so allow the MS services you mention to have access.
You can also create a private endpoint, and so add the key vault to your private Vnet.
All of this is related to networking - not being blocked by a firewall. You also need to grant permission to the service you use to access key vault, for example, with service principle or managed identity.
I tried to reproduce the same in my environment to access Azure key Vault with Private Endpoint:
I have created Vnet with required configuration.
Subnet and AddressSpace
Azure Portal > Virtual networks > Create
Create key-vault with private endpoint.
Azure Portal > Key vaults > Create a key vault
Note under Network section uncheck public access.
once create the Keyvault, check the private endpoint provisioning status, like below.
If you are trying to access the Azure Keyvault from public internet, you will get unauthorized error, like below.
Azure Keyvault is accessible with private network, like below.
For accessing Azure Datafactory using Azure keyvault, Assign service principal.
Required Role: Key Vault Reader
Keyvault access policy is assigned to ADF managed Identity.
Ex: hellotestdata
You can add Azure Key vault as a linked service in the Azure Data factory. the managed identity of the ADF that has access to key vault can be used for connecting ADF to Azure Key vault like below.
Azure Key Vault is successfully linked to ADF.

I have created a User-Assigned Managed Identity that I have assigned to a Function App. I want to replace the Access Key connection string with the User-Assigned Managed Identity for the Function App to connects to its own stage, i.e., the hosting storage for the Function App. I have given the Storage Account Contributor, Storage Blob Data Owner, Storage Queue Data Contributor and Storage Table Data Contributor roles to the User-Assigned Managed Identity. What needs to be done to replace to storage account Access Key connection string with User-Assigned Managed Identity? I have tried to renaming the configuration AzureWebJobsStorage to AzureWebJobsStorage__accountName and replacing the Access Key connection string with the storge account name, as described in this tutorial: https://learn.microsoft.com/en-us/azure/azure-functions/functions-identity-based-connections-tutorial, however this does not seem to work. I’m unable to reach the function app and get the following error in the logs: "statusCode":400,"message":"Unable to load requested managed identity.
I am using Azure Web App service. Currently, I am storing the plain connection string to the database, Azure storage in the Application Settings section in the configuration tab of the Web App Service.
Instead of storing the plain connection string in configuration. How can I store the connection string in Azure Vault, then reference it in the Application setting so that the plain connection string are not stored in the configuration settings?
There are two ways to reference Key Vault in Azure Web Apps. You can do a complete reference:
#Microsoft.KeyVault(SecretUri=https://myvault.vault.azure.net/secrets/mysecret/)
Or you can use the alterative:
#Microsoft.KeyVault(VaultName=myvault;SecretName=mysecret)
In order to read secrets from Key Vault, you need to have a vault created and give your app permission to access it.
Create a key vault by following the Key Vault quickstart.
Create a managed identity for your application.
Key Vault references will use the app's system assigned identity by default, but you can specify a user-assigned identity.
Create an access policy in Key Vault for the application identity you created earlier. Enable the "Get" secret permission on this policy. Do not configure the "authorized application" or applicationId settings, as this is not compatible with a managed identity.
Full steps on setting this up:
https://learn.microsoft.com/en-us/azure/app-service/app-service-key-vault-references
I have an external web application which has the option to access a storage account using the service principal.
I want to access Azure storage account/blob by the external application loading the data directly into the datalake account.
So here is what I am trying to do:
Set up a service principal (using Azure AD app registration)
Create a Storage account and store the access key in Azure Key Vault.
Add the service principal secret to the same key vault.
Create a policy within Key vault for the service principal to have access to read Keys and Secrets within Key Vault.
Also create a policy within Key Vault for service principal to have contributor role to access storage account.
Also grant access to storage account container to service principal.
But I cannot connect, and I am unable to authorize the connection.
I am confused on which steps I am missing to resolve this.
As you want to access the storage account using service principal, you do not need to store the storage account access in the key vault.
The steps you can follow up to access storage account by service principal:
Create a service principal (Azure AD App Registration)
Create a storage account
Assign Storage Blob Data Contributor role to the service principal
Now you would be able to access the Azure Storage Blob data using your service principal
Note: You do not need to store the service principal client secret in the key vault. Because you need the client secret again to access the key vault first.
Thanks #RamaraoAdapa-MT
This works
Finally, I setup like you said,,
SAS -> service principle -> permission to storage account -> storage account.
In this case, no need for Key vault.
Thanks you Guys,

I have my database connection string stored in Azure Key Vault as a secret. My SSIS package which is on-premises needs to read connection string from Azure Key Vault.
Usually, when I configure my SSIS package, I configure my connection string at development time and wondering how I can connect Azure Key Vault and consume a secret.
We can connect to Azure key vault from SSIS using ZappySys(Rest API Task).
Need to have below Azure key vault related information.
App registration name
Client ID
App Client Secret
Redirect URI
SecretName
