My situation is as follows: I want to create an Azure service principal. But when I try to do it with this command az ad sp create-for-rbac, I always get the error "Insufficient privileges to complete the operation."
Am I correct in assuming this appears because I was invited by a regular user to this subscription?
And in order to expand my privileges do I need to be assigned the administrator role in this subscription?
You're probably not a User Access Administrator since this is a role that needs to be set quite explicitly.
In the end, the reason is quite simple: you have "Insufficient privileges to complete the operation". You can read up on and try to Understand role definitions for Azure resources here.
az ad sp create-for-rbac requires permissions in the subscription / a resource group (Owner or User access administrator role to be specific), and in addition requires permissions in the linked Azure Active Directory to register applications (as the command creates an app registration).

I'm working with an app registration that has a secret defined. Via PowerShell I am able to get the credential, but not the secret value. Function used is Get-AzADAppCredential This is expected behavior, no issue here.
To renew the secret I run two functions Remove-AzADAppCredential and New-AzADAppCredential.
I run these PowerShell cmdlets via a DevOps pipeline and use a service connection with permissions in Azure portal.
I noticed that, when we create a service connection from DevOps to Azure, the service principal gets the role Cloud application administrator automatically assigned.
This role includes the permission "microsoft.directory/applications/credentials/update".
So the above (remove + new) should work, but it does not...
DevOps returns an error:
Az.MSGraph.internal\Remove-AzADApplicationPassword : Insufficient privileges to complete the operation.
Az.MSGraph.internal\Add-AzADApplicationPassword : Insufficient privileges to complete the operation.
PS. Using Az.Resources version 5.4.0 when working with the PowerShell functions.
Anyone got any idea what I'm missing?
Thanks.
Insufficient privileges to complete the operation.
The error comes when the user doesn't have sufficient privileges in AAD and doesn't have Write permission for the selected Azure Subscription.
Note: If you have Cloud application administrator privileges of the user, this role grants the ability to manage application credentials. Users assigned this role can add credentials to an application and use those credentials to impersonate the application’s identity. If the application’s identity has been granted access to a resource, such as the ability to create or update User or other objects, then a user assigned to this role could perform those actions while impersonating the application.
Make sure to check once if you have Global Administrator Access. If you have the access you can able to Modify the secret.
Users who are assigned to the Global administrator role can read and modify every administrative setting in your Azure AD organization.
The permission issue may happen due to
The user has only guest permission in the directory
The user is not authorized to the add applications in the directory

To be able to update a secret on an app registration, through DevOps, using a service principal, with minimal permissions, first make the service connection owner on that random app registration.
Next, add the Application.ReadWrite.OwnedBy application API permission on the app registration that's linked to the enterprise application. Not on the app registration where the service principal was made owner.
Than renewing the secret works fine.
It remains a question though why the role Cloud application administrator isn't sufficient because microsoft.directory/applications/credentials/update is included in that role, and that should also be enough.
I am updating a Powershell script to replace use of Azure CLI calls with PowerShell commands. The Powershell script creates a number of App Registrations in an Azure tenant, adds permissions to them, and then grants access to those permissions.
I am finding it difficult to replace the CLI calls granting access. Typically these calls grant a service principal access with a scope or scopes, e.g.
az ad app permission grant --id $app.appId --api 00000003-0000-0000-c000-000000000000 --scope "offline_access openid"
I see no way to do this with the Cmdlets in the Azure Resources Module, and have not been to find a direct equivalent in the Azure Graph API. The nearest thing I have found in the Graph API is an endpoint for granting an App Role Assignment (https://learn.microsoft.com/en-us/graph/api/serviceprincipal-post-approleassignedto?view=graph-rest-1.0&tabs=powershell) but that addresses a different problem, assigning roles rather than scopes.
I'm pretty new to Azure development, but I've been knocking my head off this one for a few days now, so any advice would be appreciated!
Edit: Adding an example of a permission I'd like to be able to grant where Admin Consent is not required.
We have tested this in our local environment it is working fine. Below statements are based on our analysis.
You can use the below PowerShell cmdlet to add a permission to the app registration.
Add-AzADAppPermission -ObjectId "<objectID>" -ApiId "00000003-0000-0000-c000-000000000000" -PermissionId "<PermissionId>" -Type "<role(ApplicationPermissions),Scope(DelagatedPermissions)"
Here is the sample Output screenshot for reference:
As per the Current documentation, User needs to grant consent via Azure Portal if the permission requires admin consent because Azure PowerShell doesn't support it yet.
Note :
Application permissions under the appRoles property correspond to Role in -Type. Delegated permissions under the oauth2Permissions property correspond to Scope in -Type.
I create an azure managed instance, I want to set one account to active directory admin ,But I cannot grant "read" permission to the MI like below screenshot
Obviously, you do not have an administrator role. You need to have your tenant administrator grant you the company administrator or global administrator
role.
Log in to Azure as a global administrator>Azure AD>users>select user>Assigned roles
I have a Web API that is protected by Azure AD. I have created an app registration for the Web API that only allows users from that Azure AD to access the API (i.e. single tenant). This process also created a Service Principal in that tenant.
What I am wondering is if this Service Principal can self-assign itself RBAC role (any RBAC role for that matter) in an Azure Subscription that trusts this Azure AD? Or will this be a user-initiated action where a user with appropriate permission (like Owner or User Access Administrator) has to assign appropriate role to this Service Principal?
From whatever my understanding is, I believe it is latter (i.e. another user has to perform this operation). However it looks like it should be possible though.
The reason I say this is when I create a new Azure Subscription, I am automatically assigned an Owner role in that Azure Subscription (I am a Global Administrator in my Azure AD). I am wondering how that is accomplished.
If it is indeed possible, then what Azure AD role should be assigned to the Service Principal?
Any insights into this will be highly appreciated.
Of course it can, but the service principal also needs the Microsoft.Authorization/roleAssignments/write permission e.g. Owner or User Access Administrator to assign another RBAC role to itself.
If you mean the service principal has no RBAC role currently, then it can't, even if it is a Global admin in the tenant, it could not assign the RBAC role to itself directly.
Besides, the user account is different from a service principal, if a user is a global admin in the tenant, he can simply Elevate access to manage all Azure subscriptions and management groups for himself(this just works for the user, not service principal), then he will get the User Access Administrator role at the root scope, then he can assign any RBAC role to himself.
If your service principal is a global admin and wants to assign RBAC role to itself, you may need to assign the global admin role to another user account first, then elevate access to manage all Azure subscriptions, then use the user account to assign the RBAC role to the service principal.
You are correct that a principal can only grant itself permissions when it already has rights to do so. It would follow that a brand new MSI principal would not be a member of any groups or assigned any RBAC roles and therefore could not grant itself additional rights.
In the case of an Azure Subscription, the principal which creates the subscription either has permission to do so in an existing tenant or is creating a new tenant and subscription, and rights are granted by the system to the user as the creator/owner.
A possible approach to automate granting rights to new MSIs would be to use an Azure Function, calling the Microsoft Graph to query for new MSIs matching a search criteria, then grant the MSI principal the required permissions. The Function would have to have an MSI assigned which would need permission to grant the required rights to the new MSI at the desired scope.
My requirement is simple. I want to login to Azure through my shell script in non-interactive mode, but "az login -u username -p password" command gives the following error:
Get Token request returned http error: 400 and server response: {"error":"invalid_grant","error_description":"AADSTS70002: Error validating credentials. : SAML token is invalid. : The element with ID 'xxxxxx' was either unsigned or the signature was invalid.
Some site told me to create a service principal. Now my question is, what is a service principal, and how do I create a service principal so that I can execute my commands (for creating different resources like app gateway) from my shell script?
Please refer to this official document.
An Azure service principal is a security identity used by user-created
apps, services, and automation tools to access specific Azure
resources. Think of it as a 'user identity' (login and password or
certificate) with a specific role, and tightly controlled permissions
to access your resources. It only needs to be able to do specific
things, unlike a general user identity. It improves security if you
only grant it the minimum permissions level needed to perform its
management tasks.
If you want to create a new service principal(sp) with Azure CLi 2.0. You could login with your Azure AD user. Then execute following command.
az ad sp create-for-rbac --name {appId} --password "{strong password}"
The result like below:
{
"appId": "a487e0c1-82af-47d9-9a0b-af184eb87646d",
"displayName": "MyDemoWebApp",
"name": "http://MyDemoWebApp",
"password": {strong password},
"tenant": "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
}
appId is your login user, password is login password.
After the sp is created, you also need give it Contributor role, then you could manage your Azure resource.
az role assignment create --assignee <objectID> --role Contributor
Now, you could login in non interctive mode with following command.
az login --service-principal -u <appid> --password {password-or-path-to-cert} --tenant {tenant}
Service principal just work as an impersonation for user in Azure AD. Refer - https://sanganakauthority.blogspot.com/2019/04/how-to-create-service-principal-or-app.html
Using this you can perform any type of management task against Azure using REST APIs. This way you avoid need of providing credentials in pop up and hence help to automate things in Azure using REST APIs.
Here your go: Use portal to create an Azure Active Directory application and service principal that can access resources.
When you have an application that needs to access or modify resources, you must set up an Azure Active Directory (AD) application and assign the required permissions to it. This approach is preferable to running the app under your own credentials because:
You can assign permissions to the app identity that are different than your own permissions. Typically, these permissions are restricted to exactly what the app needs to do.
You do not have to change the app's credentials if your responsibilities change.
You can use a certificate to automate authentication when executing an unattended script.
