List Azure role assignments using Azure PowerShell

  • Οδηγίες

Azure role-based access control (Azure RBAC) is the authorization system you use to manage access to Azure resources. To determine what resources users, groups, service principals, or managed identities have access to, you list their role assignments. This article describes how to list role assignments using Azure PowerShell.

Note

We recommend that you use the Azure Az PowerShell module to interact with Azure. To get started, see Install Azure PowerShell. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.

Note

If your organization has outsourced management functions to a service provider who uses Azure Lighthouse, role assignments authorized by that service provider won't be shown here. Similarly, users in the service provider tenant won't see role assignments for users in a customer's tenant, regardless of the role they've been assigned.

Prerequisites

List role assignments for the current subscription

The easiest way to get a list of all the role assignments in the current subscription (including inherited role assignments from root and management groups) is to use Get-AzRoleAssignment without any parameters.

Get-AzRoleAssignment

PS C:\> Get-AzRoleAssignment

RoleAssignmentId   : /subscriptions/00000000-0000-0000-0000-000000000000/providers/Microsoft.Authorization/roleAssignments/11111111-1111-1111-1111-111111111111
Scope              : /subscriptions/00000000-0000-0000-0000-000000000000
DisplayName        : Alain

ObjectType         : User
CanDelegate        : False

RoleAssignmentId   : /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/pharma-sales/providers/Microsoft.Authorization/roleAssignments/33333333-3333-3333-3333-333333333333

List role assignments for a subscription

To list all role assignments at a subscription scope, use Get-AzRoleAssignment. To get the subscription ID, you can find it on the Subscriptions blade in the Azure portal or you can use Get-AzSubscription.

Get-AzRoleAssignment -Scope /subscriptions/<subscription_id>

PS C:\> Get-AzRoleAssignment -Scope /subscriptions/00000000-0000-0000-0000-000000000000

List role assignments for a user

To list all the roles that are assigned to a specified user, use Get-AzRoleAssignment.

Get-AzRoleAssignment -SignInName <email_or_userprincipalname>

PS C:\> Get-AzRoleAssignment -SignInName isabella@example.com | FL DisplayName, RoleDefinitionName, Scope

DisplayName        : Isabella Simonsen
RoleDefinitionName : BizTalk Contributor
Scope              : /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/pharma-sales

To list all the roles that are assigned to a specified user and the roles that are assigned to the groups to which the user belongs, use Get-AzRoleAssignment.

Get-AzRoleAssignment -SignInName <email_or_userprincipalname> -ExpandPrincipalGroups

Get-AzRoleAssignment -SignInName isabella@example.com -ExpandPrincipalGroups | FL DisplayName, RoleDefinitionName, Scope

List role assignments for a resource group

To list all role assignments at a resource group scope, use Get-AzRoleAssignment.

Get-AzRoleAssignment -ResourceGroupName <resource_group_name>

PS C:\> Get-AzRoleAssignment -ResourceGroupName pharma-sales | FL DisplayName, RoleDefinitionName, Scope

DisplayName        : Alain Charon
RoleDefinitionName : Backup Operator
Scope              : /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/pharma-sales

DisplayName        : Isabella Simonsen
RoleDefinitionName : BizTalk Contributor
Scope              : /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/pharma-sales

DisplayName        : Alain Charon
RoleDefinitionName : Virtual Machine Contributor
Scope              : /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/pharma-sales

List role assignments for a management group

To list all role assignments at a management group scope, use Get-AzRoleAssignment. To get the management group ID, you can find it on the Management groups blade in the Azure portal or you can use Get-AzManagementGroup.

Get-AzRoleAssignment -Scope /providers/Microsoft.Management/managementGroups/<group_id>

PS C:\> Get-AzRoleAssignment -Scope /providers/Microsoft.Management/managementGroups/marketing-group

List role assignments for a resource

To list role assignments for a specific resource, use Get-AzRoleAssignment and the -Scope parameter. The scope will be different depending on the resource. To get the scope, you can run Get-AzRoleAssignment without any parameters to list all of the role assignments and then find the scope you want to list.

Get-AzRoleAssignment -Scope "/subscriptions/<subscription_id>/resourcegroups/<resource_group_name>/providers/<provider_name>/<resource_type>/<resource>

This following example shows how to list the role assignments for a storage account. Note that this command also lists role assignments at higher scopes, such as resource groups and subscriptions, that apply to this storage account.

PS C:\> Get-AzRoleAssignment -Scope "/subscriptions/00000000-0000-0000-0000-000000000000/resourcegroups/storage-test-rg/providers/Microsoft.Storage/storageAccounts/storagetest0122"

If you want to just list role assignments that are assigned directly on a resource, you can use the Where-Object command to filter the list.

PS C:\> Get-AzRoleAssignment | Where-Object {$_.Scope -eq "/subscriptions/00000000-0000-0000-0000-000000000000/resourcegroups/storage-test-rg/providers/Microsoft.Storage/storageAccounts/storagetest0122"}

List role assignments for classic service administrator and co-administrators

To list role assignments for the classic subscription administrator and co-administrators, use Get-AzRoleAssignment.

Get-AzRoleAssignment -IncludeClassicAdministrators

List role assignments for a managed identity

Follow these steps:

  1. Get the object ID of the system-assigned or user-assigned managed identity.

    To get the object ID of a user-assigned managed identity, you can use Get-AzADServicePrincipal.

    Get-AzADServicePrincipal -DisplayNameBeginsWith "<name> or <vmname>"

  2. To list the role assignments, use Get-AzRoleAssignment.

    Get-AzRoleAssignment -ObjectId <objectid>
