I am new to Azure Functions and I want to create a queue trigger Function to consume the items in specific queue. But when I create queue trigger function in vscode, it keeps show that I lack some permissions.
The client 'live.com#***#gmail.com' with object id '***' does not have authorization to perform action 'Microsoft.Storage/storageAccounts/listKeys/action' over scope '/subscriptions/**/resourceGroups/***/providers/Microsoft.Storage/storageAccounts/***' or the scope is invalid. If access was recently granted, please refresh your credentials.
The permissions I am now obtaining for this queue are as follows:
The permissions I am now obtaining for the storage account are as follows:
I am confused that which kind of permissions I need to create a queue triggered function to consume items in specific queue?
Thank you!
When creating a function from VS Code using the Azure SDK, it will try to get the access key of the storage: by default this how you can authenticate to the storage. The error you're receiving is saying that you don't have permission to list the storage access keys.
From this documentation, these are the roles that has the Microsoft.Storage/storageAccounts/listkeys/action RBAC action:
The Reader and Data Access role
The Storage Account Contributor role
The Azure Resource Manager Contributor role
The Azure Resource Manager Owner role
Azure AD roles and Azure roles are the 2 different. You have to assign the Azure roles to the applications you're working.
It means, storage contributor role on the storage account application that in turn refers you have to grant the access to the service principal which is running your application to the storage contributor role on the storage account.
Yes! As Thomas said that the permissions required to the storage account access keys along with Storage Contributor role were Reader and Data Access, ARM Contributor and ARM Owner role.
I believe any one role from the above is required, depends on the level of access you required.
Refer to Azure storage account access keys for more information.

I'm trying to set up the external location for the unity catalog. it was able to connect to storage while trying to test a connection in which storage access is limited to selected vnets and ips. but I'm getting a 403 error while accessing the storage from the notebook even adding the blob contributor access to managed identity. Did I miss anything?
my assumption is since I added a connector to the trusted resources it will bypass the network rules.
Databricks throwing 403 error
The main reason for 403 error is related to authorization issues for accessing azure storage account to avoid access related issues Assign the application to a role, make sure to assign the Storage Blob Data Contributor role to the service principal.
You need to have only (Storage Blob Data Contributor) Role specified on your storage for your service principal. To assign Storage Blob Data Contributor roles using portal follow this link.
I have created demt1 storage account for demo, open Access controls -> Role assignment
![enter image description here](https://i.imgur.com/a140fKd.png
Under Role assignment select Storage Blob Data Contributor created initially
To check if the role is assigned open Access control -> Check Access -> Check access
and search for databricks
Under Current assignments there will be assigned role
Open databricks account and try to access storage by mounting an existing container
Additional Settings
Try adding the Databricks' workspace managed identity as a Storage Blob Data Contributor.
IAM for Databricks Managed Identity
You'll also want to add the relevant IAM conditional access, such as Read / Write permissions.

I try to create a User delegation key from azure portal.
No matter what privileges I'm assigning to myself, I hit the same error message
You don't have permissions to grant read access. You can still create
a shared access signature, but you'll need an RBAC role with
additional permissions before you can grant that level of access to
your signature recipient.Learn more about Azure roles for access to
blob data
So far I have the following the roles assigned :
And the link provided in the error message says I need one of the following :
Contributor
Storage Account Contributor
Storage Blob Data Contributor
Storage Blob Data Owner
Storage Blob Data Reader
Storage Blob Delegator
So it should work, but it doesn't. What am I missing ?
The error usually occurs if you don't have required roles/permissions assigned to create User delegation key.
Please note that in order to create user delegation key, ensure to have role that includes action like below:
Microsoft.Storage/storageAccounts/blobServices/generateUserDelegationKey
The above action is included in the below roles:
Storage Blob Data Contributor
Storage Blob Data Owner
Storage Blob Data Reader
Storage Blob Delegator
Try assigning either Storage Blob Data Contributor / Storage Blob Data Owner roles as you didn't assign.
Please check at what scope you have assigned the role, make sure to assign the roles at the level of the storage account, the resource group, or the subscription.
I tried in my environment, and got the same error when the roles are not assigned:
After assigning the roles, I am able to create user delegation key successfully without errors.
If still the error persists, try creating an Azure Support ticket.

I am working on an Azure application that gets the resources in a subscription, and then gets some information on them, e.g. get all the storage resources then get all the properties for them.
storage_client = StorageManagementClient(
session.client_secret_credentials,
session.subscription_id,
api_version="2021-06-01",
)
storage_account: StorageAccount = storage_client.storage_accounts.get_properties(
resource_group,
storage_account_id,
)
I want the app to have the minimum permissions so that it can only get the existence and information about the resource but not read the contents of the resource at all.
The application does a similar thing in AWS where it uses the security audit role.
Is there are role in Azure that can do this? If not is it possible to create one? All the MS documentation I have looked at just talks about Read permissions which does not seem what I want.
Reader permission on a Storage account does not allow you access to the contents of the Storage account.
There are separate roles/permissions for data access.
Of course there are also access keys but to get them the app would need Write permissions to the Storage account.
You can read more here: https://learn.microsoft.com/en-us/azure/storage/blobs/assign-azure-role-data-access?tabs=portal#assign-an-azure-role
The Reader role is an Azure Resource Manager role that permits users
to view storage account resources, but not modify them. It does not
provide read permissions to data in Azure Storage, but only to account
management resources.
I know how to create service principal for app registration. However, what is "Azure Service principal account" for read-only Azure access?
The requirement is to execute API or make API call from a framework or run the command for Azure Infra and Service validation.
The additional details:
account with id and secret key?
Account with IAM privilege to read config data from Azure services?
Access to cloud providers API for config validation?
Is there any stpes to do this? It will be really helpful if the above details can be done from Azure portal.
On Work around To create the azure service principal for read only access You can try with using the Azure CLI
. The Reader role is more restrictive, with read-only access. For more information on Role-Based Access Control (RBAC) and roles, see this document RBAC: Built-in roles.
When restricting a service principal's permissions, the Contributor role should be removed.
This example adds the Reader role and removes the Contributor role:
az role assignment create --assignee APP_ID --role Reader
az role assignment delete --assignee APP_ID --role Contributor
Note: If your account doesn't have permission to assign a role, you see an error message that your account does not have authorization to perform action 'Microsoft.Authorization/roleAssignments/write'. Contact your Azure Active Directory admin to manage roles.
Microsoft recommends to use the Contributor role at minimum for a service principal. This role has full permissions to read and write to an Azure account.
For more information refer this Microsoft doc :
Im working on an Azure function that tries to get and update a client secret for an Azure app registration. Function runs as a managed identity, and tries to execute Azure powershell cmdlet New-AzADAppCredential, Remove-AzADAppCredential, and Get-AzADAppCredential.
But, upon the execution Im getting an error Insufficient privileges to complete the operation.
I tried assigning my function a Contributor role, under Azure role assignments, and I also tried giving a delegated permissions Directory.ReadWrite.All for an app registration that the function is trying to access. However, Im still seeing the same error.
I would like to know what permissions are necessary for a managed identity azure function to be able to manage an app registration client secrets.
Thanks!
The RBAC roles are used to manage resources in azure subscriptions, in this case, what you need is the permission in Azure AD, not in the subscription.
To fix the issue, the easiest way is to give the Application Administrator to your managed identity.
Navigate to the azure portal -> Azure Active Directory -> Roles and administrators -> Application Administrator -> add the managed identity to the role like below.
The Contributor role allows the assignee to manage and access the resource, but as you have discovered that does not include managing access. Similarly, Directory.ReadWrite.All is for user data not RBAC. There are two roles for RBAC- Owner and User Access Administrator. Owner is Contributor and UA Admin only allows access control.
