using namespace System.Management.Automation.Language <# .Description This function lists all Graph, SharePoint or Exchange permissions required for the specified resources, both for reading/updating and Delegated/Applications.

The provided permissions have to be as an array of hashtables, with Api=Graph, SharePoint or Exchange and PermissionsName set to a list of permissions. See examples for more information. NOTE: Please make sure you have the following permissions for the 'Microsoft Graph Command Line Tools' Enterprise Application in your tenant: - Application.ReadWrite.All You can add this scope to the 'Microsoft Graph Command Line Tools' Enterprise Application by running the following command: ```powershell Connect-MgGraph -Scopes 'Application.ReadWrite.All' ``` NOTE: If consent cannot be given for whatever reason, make sure all these permissions are given Admin Consent by browsing to the App Registration in Azure AD > API Permissions and clicking the "Grant admin consent for <orgname>" button.

Default value is 'Microsoft365DSC'. .Parameter Permissions The permissions to assign to the application. This has to be an array of hashtables, with Api=Graph, SharePoint or Exchange and PermissionsName set to a list of permissions. See examples for more information. .Parameter Type The type of credential to create. Default value is 'Secret'. Valid values are 'Secret' and 'Certificate'. .Parameter MonthsValid The number of months the certificate should be valid. Default value is 12. .Parameter CreateNewSecret If specified, a new secret will be created for the application. -CreateNewSecret or -CertificatePath can be used, not both. .Parameter CertificatePath The path to the certificate to be uploaded for the app registration. If using with -CreateSelfSignedCertificate - a file with this name will be created and uploaded (file must not exist). Otherwise the file must already exist. Cannot be used with -CreateNewSecret simultaneously. .Parameter CreateSelfSignedCertificate If specified, a self-signed certificate will be created for the application. -CreateSelfSignedCertificate or -CertificatePath can be used, not both. .Parameter AdminConsent If specified, admin consent will be granted for the application. .Parameter Credential The credential to use for authenticating the request. Mutually exclusive with -TenantId. .Parameter ApplicationId The ApplicationId to use for authenticating the request. -Credential or -ApplicationId can be used, not both. .Parameter TenantId The name of the tenant to use for the request. Must be in the form of contoso.onmicrosoft.com. Mutually exclusive with -Credential. .Parameter ApplicationSecret The ApplicationSecret to use for authenticating the request. -Credential or -ApplicationSecret can be used, not both. .Parameter CertificateThumbprint Thumbprint of an existing auth certificate to use for authenticating the request. Mutually exclusive with -Credential. .Parameter ManagedIdentity If specified, Managed Identity will be used for authenticating the request. -Credential or -ApplicationId or -ManagedIdentity can be used, only one of them. .Example Update-M365DSCAzureAdApplication -ApplicationName 'Microsoft365DSC' -Permissions @(@{Api='SharePoint';PermissionName='Sites.FullControl.All'}) -AdminConsent -Type Secret -Credential $creds .EXAMPLE Update-M365DSCAzureAdApplication -ApplicationName 'Microsoft365DSC' -Permissions @(@{Api='Graph';PermissionName='Domain.Read.All'}) -AdminConsent -Credential $creds -Type Certificate -CreateSelfSignedCertificate -CertificatePath c:\Temp\M365DSC.cer .EXAMPLE Update-M365DSCAzureAdApplication -ApplicationName 'Microsoft365DSC' -Permissions @(@{Api='SharePoint';PermissionName='Sites.FullControl.All'},@{Api='Graph';PermissionName='Group.ReadWrite.All'},@{Api='Exchange';PermissionName='Exchange.ManageAsApp'}) -AdminConsent -Credential $creds -Type Certificate -CertificatePath c:\Temp\M365DSC.cer .EXAMPLE Update-M365DSCAzureAdApplication -ApplicationName $Microsoft365DSC -Permissions $(Get-M365DSCCompiledPermissionList -ResourceNameList Get-M365DSCAllResources -PermissionType Application -AccessType Read) -Type Certificate -CreateSelfSignedCertificate -AdminConsent -MonthsValid 12 -Credential $creds -CertificatePath c:\Temp\M365DSC.cer .Functionality Public #> function Update-M365DSCAzureAdApplication { [CmdletBinding(DefaultParameterSetName = 'Secret')] param ( [Parameter(ParameterSetName = 'Secret')] [Parameter(ParameterSetName = 'Certificate')] [System.String] $ApplicationName = 'Microsoft365DSC', [Parameter(Mandatory = $true, ParameterSetName = 'Secret')] [Parameter(Mandatory = $true, ParameterSetName = 'Certificate')] [System.Collections.Hashtable[]] $Permissions, [Parameter(ParameterSetName = 'Secret')] [Parameter(ParameterSetName = 'Certificate')] [ValidateSet('Secret', 'Certificate')] [System.String] $Type = 'Secret', [Parameter(ParameterSetName = 'Secret')] [Parameter(ParameterSetName = 'Certificate')] [System.Int32] $MonthsValid = 12, [Parameter(ParameterSetName = 'Secret')] [Switch] $CreateNewSecret, [Parameter(ParameterSetName = 'Certificate')] [System.String] $CertificatePath, [Parameter(ParameterSetName = 'Certificate')] [Switch] $CreateSelfSignedCertificate, [Parameter(ParameterSetName = 'Secret')] [Parameter(ParameterSetName = 'Certificate')] [Switch] $AdminConsent, [Parameter()] [System.Management.Automation.PSCredential] $Credential, [Parameter()] [System.String] $ApplicationId, [Parameter()] [System.String] $TenantId, [Parameter()] [System.Management.Automation.PSCredential] $ApplicationSecret, [Parameter()] [System.String] $CertificateThumbprint, [Parameter()] [Switch] $ManagedIdentity ) function Write-LogEntry { param ( [Parameter(Mandatory = $true)] [System.String] $Message, [Parameter()] [ValidateSet('Error', 'Warning', 'Info')] [System.String] $Type = 'Info' ) $timestamp = Get-Date -Format 'yyyy-MM-dd HH:mm:ss' switch ($Type) { 'Error' { $params = @{ Object = ('{0} - [ERROR] {1}' -f $timestamp, $Message) ForegroundColor = 'Red' } } 'Warning' { $params = @{ Object = ('{0} - [WARNING] {1}' -f $timestamp, $Message) ForegroundColor = 'Yellow' } } 'Info' { $params = @{ Object = ('{0} - {1}' -f $timestamp, $Message) ForegroundColor = 'White' } } } Write-Host @params } $ConnectionMode = New-M365DSCConnection -Workload 'MicrosoftGraph' ` -InboundParameters $PSBoundParameters $requireWait = $false Write-LogEntry -Message 'Checking specified parameters' switch ($Type) { 'Secret' { Write-LogEntry -Message ' Using a Secret as credential' } 'Certificate' { Write-LogEntry -Message ' Using a Certificate as credential' Write-LogEntry -Message ' ' Write-LogEntry -Message ' Make sure your certificate has the following prerequisites:' Write-LogEntry -Message ' KeySpec : Signature' Write-LogEntry -Message ' KeyLength : 2048' Write-LogEntry -Message ' KeyAlgorithm : RSA' Write-LogEntry -Message ' HashAlgorithm : SHA256 or SHA1' Write-LogEntry -Message ' Enhanced Key Uses : Client Authentication and Server Authentication' Write-LogEntry -Message ' And the entire certificate chain is available!'
