Azure Active Directory – How to give a Registered Application an AD Directory Administrative Role

By default a ‘Registered Application’ account is not a member of any Directory Roles and/or group memberships and there is no easy way to make these changes using the portal. You may have an API or back-end application that will be required to perform actions on your AD that requires elevated permissions (e.g. Reset passwords or delete accounts etc..)

Normally for advanced configuration, you will need to start editing the manifest file. Luckily this has been made easy using the Portal. You can now edit the file directly, or download, make changes and then upload.

However, to make a ‘Registered Application’ a member of a ‘Directory Administrative Role’ you need to use PowerShell to add the role member to the ‘Service Principal’ (as I couldn’t find a way to do this in the manifest!).

Let’s Encrypt Extension for Azure App Services

Let’s Encrypt Extension for Azure App Services

Thanks to Simon J.K. Pedersen (https://github.com/sjkp) there is now a reasonably easy way to get auto-updating “Let’s Encrypt” SSL certificates in you Azure App Services using the “Azure Let’s Encrypt” Extension (https://github.com/sjkp/letsencrypt-siteextension).

There are some very comprehensive install and setup steps here https://github.com/sjkp/letsencrypt-siteextension/wiki/How-to-install

How to delete an Azure Active Directory (ADD) Tenant

You may have discovered that deleting an Azure Active Directory is a particularly frustrating experience that ultimately ends in failure. The new portal have improved things a bit, by running through a series of check before the delete button is enabled.

You may need to go back to the Classic portal (https://manage.windowsazure.com) to see some of the objects/resources to delete.

However, although this will help you remove ‘most’ of what you need to, unfortunately NOT all!

In this case I got a “Unable to delete directory

How to add Open Source License to your GitHub repository

When you first create a new repository in GitHub, you get a very handy drop down of Open Source Licenses options to add. This is really useful and saves you trying to find the standard copy somewhere.

If you don’t choose one when you create the repo, then there is a sneaky way to get that drop down back and easily add a standard license file later. Continue reading “How to add Open Source License to your GitHub repository”

Azure App Service – Force redirect from HTTP to HTTPS the easy way!

Once you have uploaded your SSL certificates to your Azure App Service and then configured the bindings (if you are using your own custom domains), there are two ways to force ALL requests to be redirected  from HTTP to HTTPS. The ‘Developer way‘ and the ‘Easy, no code way‘! Continue reading “Azure App Service – Force redirect from HTTP to HTTPS the easy way!”

Creating an Azure Virtual Network with VPN Gateway entirely with PowerShell not possible!

As I found the documentation for this somewhat lacking (especially for New-AzureRmVirtualNetworkGateway and New-AzureRmVirtualNetworkGatewayIpConfig), I thought I would try and see if it was possible to create and fully configure a Virtual Network and Gateway using PowerShell. I have posted my PowerShell script examples and efforst here.

NOTE: Several of these command return  a warning (shown below) which means things will be changing soon…again 😉 …and other just exception, so although you can setup a Virtual Network you can not create the Gateway!

I am using version 3.3.0 of the Azure cmdlets.

# Get Azure cmdlets version
Get-Module -ListAvailable -Name Azure -Refresh

Steps

  1. Setup variables, login and set current context
    # Setup Variables
    $location = "North Europe"
    $rgName = "MyResourceGroup"
    $strgAccount = "MyStorageAccount"
    $vnetName = "vnet-1"
    $gatewayPIPName = "gateway-2-pip"
    $clientAddressPool = "192.168.0.0/16"
    $gatewayName = "mygateway1"
    
    # Setup PowerShell Environment
    Add-AzureRmAccount
    Select-AzureRmSubscription -SubscriptionName "MySubscription"
    Set-AzureRmCurrentStorageAccount -ResourceGroupName $rgName -Name $strgAccount
    # get and check current context (ARM)
    Get-AzureRmContext
  2. Create the Virtual Network (include a subnet called ‘GatewaySubnet‘ specifically for the VPN Gateway. It appears this is required even if using the Portal to add a Gateway to a Virtual Network.)
    # Create the Virtual Network with 3 subnets)
    # Setup Subnets
    $gatewaySubnet = New-AzureRmVirtualNetworkSubnetConfig `
        -Name GatewaySubnet -AddressPrefix "10.1.0.0/24"
    $frontendSubnet = New-AzureRmVirtualNetworkSubnetConfig `
        -Name frontendSubnet -AddressPrefix "10.1.1.0/24"
    $backendSubnet = New-AzureRmVirtualNetworkSubnetConfig `
        -Name backendSubnet -AddressPrefix "10.1.2.0/24"
    # Create VNet
    $vnet = New-AzureRmVirtualNetwork -Name $vnetName `
        -ResourceGroupName $rgName -Location $location `
        -AddressPrefix "10.1.0.0/16" `
        -Subnet $gatewaySubnet,$frontendSubnet,$backendSubnet
  3. Create a Public IP Address (PIP) to be used by the Gateway
    # Create a PIP
    $pip = New-AzureRmPublicIpAddress -AllocationMethod Dynamic `
        -ResourceGroupName $rgName -Location $location `
        -Name $gatewayPIPName
  4. Create the VNet Gateway (Attempt 1Although I can’t see any issues in the script below, unfortunately this is returning a 500 Internal Server Error. I have tried a number of variations!!)
    # Gateway config
    $vnetGatewayIPConf = New-AzureRmVirtualNetworkGatewayIpConfig -Name default `
        -PublicIpAddress $pip -Subnet $gatewaySubnet
    # Create VNet Gateway
    $vnetGateway = New-AzureRmVirtualNetworkGateway -Name "hmstraingateway1" 
        -ResourceGroupName $rgName `
        -Location $location `
        -IpConfigurations $vnetGatewayIPConf `
        -GatewayType Vpn `
        -VpnType RouteBased `
        -GatewaySku Basic `
        -VpnClientAddressPool $clientAddressPool

     

Attempt 2: I then thought I would see if it would be possible to complete the process using ARM Templates. When attempting to get an ARM Template for an existing Virtual Network Gateway we get the following errors.

Error details - Microsoft Azure 
  • The schema of resource type 'Microsoft.Network/virtualNetworkGateways' is 
    not available. Resources of this type will not be exported to the template. 
    (Code: ResourceTypeSchemaNotFound)
  • The schema of resource type 'Microsoft.Web/connections' is not available. 
    Resources of this type will not be exported to the template. 
    (Code: ResourceTypeSchemaNotFound)

This effectively indicates that the ARM capability of this type of resource is not yet all there in Azure. I seem to come across issue like this quite a lot.

Also with the ARM Virtual Network you can’t use the Get-AzureVNetConfig to download the configuration files either.

So in conclusion the only way to currently create a Gateway and complete the process, is to use the Azure Portal. Please comment below if you know of another way or have spotted an issue.
