.SYNOPSIS Sets the ACL (Access Control List) of an ADCS (Active Directory Certificate Services) certificate template. .DESCRIPTION This function sets the ACL of an ADCS certificate template based on the specified name and provided input (JSON or object). It supports updating owner, group, DACLs (Discretionary Access Control Lists), and SACLs (System Access Control Lists). .PARAMETER Name Specifies the name of the ADCS certificate template to update. .PARAMETER Json Specifies the JSON string representing the ACL properties to update. .PARAMETER InputObject Specifies the object representing the ACL properties to update. .PARAMETER ImportInheritedAce Specifies if inherited aces should be imported. .PARAMETER PassThru If specified, the function returns the updated ACL object. .PARAMETER Server Specifies the Active Directory server to connect to. If not specified, the default server is used. .EXAMPLE PS C:\> $aclJson = @" { "Owner": "domain\User1", "Group": "domain\Group1", "DACLs": [ { "IdentityReference": "domain\User2", "ActiveDirectoryRights": "GenericRead", "AccessControlType": "Allow", "ObjectType": "00000000-0000-0000-0000-000000000000", "InheritanceType": "None", "InheritedObjectType": "00000000-0000-0000-0000-000000000000" } ], "SACLs": [], "AreAccessRulesProtected": $true, "AreAuditRulesProtected": $true } "@ PS C:\> Set-ADCSTemplateAcl -Name "UserTemplate" -Json $aclJson This example sets the ACL of the certificate template named "UserTemplate" using a JSON input. #> Function Set-ADCSTemplateAcl { [CmdletBinding(SupportsShouldProcess = $true)] [OutputType('ADCSTemplateAcl')] param( [Parameter( Mandatory = $true, Position = 0, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true )] [ValidateNotNullOrEmpty()] [SupportsWildcards()] [System.String]$Name, [Parameter(Mandatory = $true, ParameterSetName = 'Json')] [ValidateNotNullOrEmpty()] [System.String]$Json, [Parameter(Mandatory = $true, ParameterSetName = 'InputObject')] [ValidateNotNullOrEmpty()] [System.Object]$InputObject, [Parameter()] [switch]$ImportInheritedAce = $false, [Parameter(Mandatory = $false)] [switch]$PassThru = $false, [Parameter(Mandatory = $false)] [ValidateNotNullOrEmpty()] [System.String]$Server ) Begin { $ErrorActionPreference = 'Stop' $common = @{} if ($PSBoundParameters.ContainsKey('Server')) { $common.Server = $server } if ($PSBoundParameters.ContainsKey('Json')) { $InputObject = $Json | ConvertFrom-Json } New-PSDrive @common -Name CUSTOMAD -PSProvider ActiveDirectory -Root "" -WhatIf:$false | Out-Null } process { $templates = Get-ADCSTemplate @common -Name $Name foreach ($template in $templates) { $newAcl = New-Object System.DirectoryServices.ActiveDirectorySecurity if (-not [string]::IsNullOrEmpty($InputObject.Owner)) { $principal = New-Object System.Security.Principal.NTAccount($InputObject.Owner) $owner = $principal.Translate([System.Security.Principal.SecurityIdentifier]) $newAcl.SetOwner($owner) } if (-not [string]::IsNullOrEmpty($InputObject.Group)) { $principal = New-Object System.Security.Principal.NTAccount($InputObject.Group) $group = $principal.Translate([System.Security.Principal.SecurityIdentifier]) $newAcl.SetGroup($group) } foreach ($ace in $InputObject.DACLs) { if (($ImportInheritedAce -eq $false) -and ($ace.IsInherited -eq $true)) { continue } $principal = New-Object System.Security.Principal.NTAccount($ace.IdentityReference) $identityReference = $principal.Translate([System.Security.Principal.SecurityIdentifier]) $activeDirectoryRights = [System.DirectoryServices.ActiveDirectoryRights]$ace.ActiveDirectoryRights $accessControlType = [System.Security.AccessControl.AccessControlType]$ace.AccessControlType $inheritanceType = [System.DirectoryServices.ActiveDirectorySecurityInheritance]$ace.InheritanceType if (Test-IsGuid -guidString $ace.ObjectType) { $objectType = [System.Guid]$ace.ObjectType } else { $objectType = Resolve-SchemaRightsGuid @common -ObjectName $ace.ObjectType } if (Test-IsGuid -guidString $ace.InheritedObjectType) { $inheritedObjectType = [System.Guid]$ace.InheritedObjectType } else { $inheritedObjectType = Resolve-SchemaRightsGuid @common -ObjectName $ace.ObjectType } $Rule = [System.DirectoryServices.ActiveDirectoryAccessRule]::new( $identityReference, $activeDirectoryRights, $accessControlType, $objectType, $inheritanceType, $inheritedObjectType );
