Function Connect-IDMGraphApp { <# .SYNOPSIS Authenticates to the Graph API via the Microsoft.Graph.Intune module using app-based authentication. .DESCRIPTION The Connect-IDMGraphApp cmdlet is a wrapper cmdlet that helps authenticate to the Graph API using the Microsoft.Graph.Intune module. It leverages an Azure AD app ID and app secret for authentication. See https://oofhours.com/2019/11/29/app-based-authentication-with-intune/ for more information. https://docs.microsoft.com/en-us/azure/active-directory/develop/howto-create-service-principal-portal#create-a-new-application-secret .PARAMETER Tenant Specifies the tenant (e.g. contoso.onmicrosoft.com) to which to authenticate. .PARAMETER AppId Specifies the Azure AD app ID (GUID) for the application that will be used to authenticate. .PARAMETER AppSecret Specifies the Azure AD app secret corresponding to the app ID that will be used to authenticate. .EXAMPLE Connect-IDMGraphApp -TenantId $TenantID -AppId $app -AppSecret $secret #> [cmdletbinding()] param ( [Parameter(Mandatory=$true)] [Alias('ClientId')] [String]$AppId, [Parameter(Mandatory=$true)] [Alias('Tenant')] [String]$TenantID, [Parameter(Mandatory=$true)] [Alias('ClientSecret')] [String]$AppSecret ) try { #convert secret into creds $azurePassword = ConvertTo-SecureString $AppSecret -AsPlainText -Force $psCred = New-Object System.Management.Automation.PSCredential($AppId , $azurePassword) #connect to Azure using App service principal Connect-AzAccount -Credential $psCred -TenantId $TenantID -ServicePrincipal | Out-Null #Grab the Azure context which will include Azure Token $context = [Microsoft.Azure.Commands.Common.Authentication.Abstractions.AzureRmProfileProvider]::Instance.Profile.DefaultContext $aadToken = [Microsoft.Azure.Commands.Common.Authentication.AzureSession]::Instance.AuthenticationFactory.Authenticate($context.Account, ` $context.Environment, $context.Tenant.Id.ToString(), $null, [Microsoft.Azure.Commands.Common.Authentication.ShowDialog]::Never, ` $null, "https://graph.windows.net").AccessToken $Body = @{ Grant_Type = "client_credentials" Scope = "https://graph.microsoft.com/.default" client_Id = $AppId Client_Secret = $AppSecret } $ConnectGraph = Invoke-RestMethod -Uri "https://login.microsoftonline.com/$TenantID/oauth2/v2.0/token" -Method POST -Body $Body $token = $ConnectGraph.access_token #format the date correctly $ExpiresOnMinutes = $ConnectGraph.expires_in / 60 $ExpiresOn = (Get-Date).AddMinutes($ExpiresOnMinutes).ToString("M/d/yyyy hh:mm tt +00:00") # Creating header for Authorization token $authHeader = @{ 'Content-Type'='application/json' 'Authorization'="Bearer " + $token 'ExpiresOn'=$ExpiresOn } return $authHeader } Catch{ Write-Error ("{0}: {1}" -f $_.Exception.ItemName, $_.Exception.Message) } } function Get-IDMGraphAuthToken{ <# .SYNOPSIS This function is used to authenticate with the Graph API REST interface .DESCRIPTION The function authenticate with the Graph API Interface with the tenant name .PARAMETER User Must be in UPN format (email).
