Good Workaround!

Today i learned that querying the Microsoft Graph for the all users with manager reference is slow

What should be a fairly straight forward select is not straight forward. Talking to the product group, this is on the horizon, but right now, this must be done through slow means.

PowerShell cmdlet to get attributes not matching between two objects

This is a very quick cmdlet for getting attributes that does not match between two objects

<#
.Synopsis
   Returns a list of all attributes that does not match between two objects
#>
function Get-MismatchedAttributes
{
    [CmdletBinding()]
    [OutputType([boolean])]
    Param
    (
        [Parameter(Mandatory=$true,
                    ValueFromPipelineByPropertyName=$false,
                    Position=0)]
        $ReferenceObject,
              
        [Parameter(Mandatory=$true,
                    ValueFromPipelineByPropertyName=$false,
                    Position=1)]
        $DifferenceObject,

        [Parameter(Mandatory=$false,
                    ValueFromPipelineByPropertyName=$false,
                    Position=2)]
        [String[]] $Attributes = $null
    )

    if($Attributes -eq $null) {
        $Attributes = @(
            $ReferenceObject | gm -MemberType NoteProperty | select -exp Name
            $DifferenceObject | gm -MemberType NoteProperty | select -exp Name
        ) | Sort -Unique
    }
    
    $Attributes | Where {$ReferenceObject.$($_) -ne $DifferenceObject.$($_)}
}



$obj1 = [PSCustomObject] @{
    Attr1 = "abc"
    Attr2 = "def"
    Attr3 = "klm"
}

$obj2 = [PSCustomObject] @{
    Attr1 = "abc"
    Attr2 = "okj"

Quick PowerShell cmdlet to get query parameters sent to localhost

When testing Azure AD applications or showing of things such as implicit flow, authorization code flow etc., it can be very useful to have a listener going on localhost in order to provide the browser a valid redirect url. The following cmdlet can be used to do this, without the need to install anything.

function Get-HttpQueryParametersSentToLocalhost
{
    [CmdletBinding()]
    Param
    (
        [Parameter(Mandatory=$false,
                   ValueFromPipelineByPropertyName=$true,
                   Position=0)]
        [int] $Port = 8080,

        [Parameter(Mandatory=$false,
                   ValueFromPipelineByPropertyName=$true,
                   Position=1)]
        [string] $Response = "Done"
    )

    $listener = New-Object System.Net.HttpListener
    $listener.Prefixes.Add("http://localhost:$Port/")
    Write-verbose "Waiting for request at http://localhost:$Port/"
    $listener.Start()
    $context = $listener.GetContext()
    $Content = [System.Text.Encoding]::UTF8.GetBytes($Response)
    $Context.Response.OutputStream.Write($Content, 0, $Content.Length)
    $Context.Response.Close()
    $listener.Dispose()
    $Context.Request.RawUrl -split "[?&]" -like "*=*" | foreach -Begin {$h = @{}} -Process {$h[($_ -split "=",2 | select -index 0)] = ($_ -split "=",2 | select -index 1)} -End {$h}
    
}

$parameters = Get-HttpQueryParametersSentToLocalhost -Verbose -Port 8080
$parameters | Out-GridView

How, try to do to http://localhost:8080/asd/?test=a&idtoken=asdd&code=123 and check out what happens in PowerShell. 🙂

Ill create a new blog post that uses this to demonstrate different OpenID Connect flows later.

Building a multi tenant Azure AD application with roles

Through this blog post I will show how to build a multi tenant Azure AD application, where your customers can control role assignments through regular Azure AD app roles that they again can manage through Azure AD Entitlement Management, Access Reviews and dynamically assigned through dynamic groups.

The point of doing this kind of implementation is that you can externalize role management to the customer’s Azure AD, so that the customer can use all the great Azure AD features that exist for governing access, rather than needing to have yet another interface (your application) for assigning roles.

Clearing an attribute for all users through Microsoft Graph

Certain Azure AD attributes, such as businessPhones, are not available through the Azure AD PowerShell module. Here is a super quick way to work with the graph using PowerShell, without needing separate app registrations etc.
