Description
Use the Get-AzRoleAssignment command to list all role assignments that are effective on a scope. Without any parameters, this command returns all the role assignments made under the subscription. This list can be filtered using filtering parameters for principal, role and scope. The subject of the assignment must be specified. To specify a user, use SignInName or Microsoft Entra ObjectId parameters. To specify a security group, use Microsoft Entra ObjectId parameter. And to specify a Microsoft Entra application, use ServicePrincipalName or ObjectId parameters. The role that is being assigned must be specified using the RoleDefinitionName parameter. The scope at which access is being granted may be specified. It defaults to the selected subscription. The scope of the assignment can be specified using one of the following parameter combinations a. Scope - This is the fully qualified scope starting with /subscriptions/<subscriptionId>. This will filter assignments that are effective at that particular scope i.e. all assignments at that scope and above. b. ResourceGroupName - Name of any resource group under the subscription. This will filter assignments effective at the specified resource group c. ResourceName, ResourceType, ResourceGroupName and (optionally) ParentResource - Identifies a particular resource under the subscription and will filter assignments effective at that resource scope. To determine what access a particular user has in the subscription, use the ExpandPrincipalGroups switch. This will list all roles assigned to the user, and to the groups that the user is member of. Use the IncludeClassicAdministrators switch to also display the subscription admins and co-admins.
