function Set-AdAclCreateDeleteGroup { <# .SYNOPSIS Delegates permissions to a group for creating and deleting Group objects in an OU. .DESCRIPTION The Set-AdAclCreateDeleteGroup function delegates the necessary Active Directory permissions to allow a specified group to create and delete group objects within a specified container or organizational unit (OU). The function adds two Access Control Entries (ACEs) to the specified OU: 1. An ACE granting GenericAll rights to group objects, which enables full control over group objects 2. An ACE granting CreateChild and DeleteChild rights specifically for group objects These permissions allow the delegated group to create new groups, delete existing groups, and manage all properties of groups within the specified OU. When the -RemoveRule parameter is used, the function removes these permissions instead of granting them. .PARAMETER Group Identity of the group getting the delegation. Can be specified as SamAccountName, DistinguishedName, ObjectGUID, or SID. .PARAMETER LDAPpath Distinguished Name of the object (or container) where the permissions are going to be configured. This is typically an Organizational Unit. .PARAMETER RemoveRule If present, the access rule will be removed instead of being added. .PARAMETER Force If present, the function will not ask for confirmation when performing actions. .EXAMPLE Set-AdAclCreateDeleteGroup -Group "SG_SiteAdmins_XXXX" -LDAPPath "OU=Groups,OU=XXXX,OU=Sites,DC=EguibarIT,DC=local" Delegates the permissions for the group "SG_SiteAdmins_XXXX" to create and delete group objects in the specified OU. .EXAMPLE Set-AdAclCreateDeleteGroup -Group "SG_SiteAdmins_XXXX" -LDAPPath "OU=Groups,OU=XXXX,OU=Sites,DC=EguibarIT,DC=local" -RemoveRule Removes the permissions for the group "SG_SiteAdmins_XXXX" to create and delete group objects in the specified OU. .EXAMPLE $Splat = @{ Group = "SG_SiteAdmins_XXXX" LDAPPath = "OU=Groups,OU=XXXX,OU=Sites,DC=EguibarIT,DC=local" Force = $true } Set-AdAclCreateDeleteGroup @Splat Delegates the permissions without prompting for confirmation. .INPUTS System.String for Group and LDAPpath parameters. .OUTPUTS System.Void .NOTES Used Functions: Name ║ Module/Namespace ═══════════════════════════════════════════╬══════════════════════════════ Set-AclConstructor5 ║ EguibarIT.DelegationPS Get-AttributeSchemaHashTable ║ EguibarIT.DelegationPS Get-FunctionDisplay ║ EguibarIT.DelegationPS Get-AdObjectType ║ EguibarIT.DelegationPS Write-Verbose ║ Microsoft.PowerShell.Utility Test-IsValidDN ║ EguibarIT.DelegationPS .NOTES Version: 2.0 DateModified: 22/May/2025 LastModifiedBy: Vicente Rodriguez Eguibar vicente@eguibar.com Eguibar IT http://www.eguibarit.com .LINK https://github.com/vreguibar/EguibarIT.DelegationPS .COMPONENT Active Directory .ROLE Security .FUNCTIONALITY Group Management, Delegation of Control #> [CmdletBinding(SupportsShouldProcess = $true, ConfirmImpact = 'Medium')] [OutputType([void])] param ( # PARAM1 STRING for the Delegated Group Name [Parameter(Mandatory = $true, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true, HelpMessage = 'Group Name which will get the delegation', Position = 0)] [ValidateNotNullOrEmpty()] [Alias('IdentityReference', 'Identity', 'Trustee', 'GroupID')] $Group, #PARAM2 Distinguished Name of the OU were the groups can be changed [Parameter(Mandatory = $true, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true, HelpMessage = 'Distinguished Name of the OU were the groups can be changed', Position = 1)] [ValidateNotNullOrEmpty()] [ValidateScript({ Test-IsValidDN -ObjectDN $_ }, ErrorMessage = 'DistinguishedName provided is not valid!
