# Constructor W/6 attributes https://msdn.microsoft.com/en-us/library/w72e8e69.aspx function Set-AclConstructor6 { <# .Synopsis Modifies ACLs on Active Directory objects. .DESCRIPTION This function adds or removes access rules to an Active Directory object using a constructor with 6 parameters to specify the access rule details. .PARAMETER Id Specifies the SamAccountName of the delegated group or user. This is the identity for which the access rule will be modified. It can be a variable containing the AD group. .PARAMETER LDAPPath Specifies the LDAP path of the target Active Directory object. .PARAMETER AdRight Specifies the Active Directory rights. Valid options include CreateChild, DeleteChild, and others. .PARAMETER AccessControlType Specifies whether the access control is to Allow or Deny. .PARAMETER ObjectType Specifies the object type GUID. Use for specific property access or extended rights. .PARAMETER RemoveRule If specified, the access rule will be removed. If omitted, the access rule will be added. .PARAMETER AdSecurityInheritance Security inheritance of the new right (All, Children, Descendents, None, SelfAndChildren) .PARAMETER InheritedObjectType [GUID] of the Inherited object or Extended Right .EXAMPLE Set-AclConstructor6 -Id "SG_SiteAdmins_XXXX" -LDAPPath "OU=Users,OU=XXXX,OU=Sites,DC=EguibarIT,DC=local" -AdRight "CreateChild,DeleteChild" -AccessControlType "Allow" -InheritedObjectType 12345678-abcd-1234-abcd-0123456789012 -ObjectType 12345678-abcd-1234-abcd-0123456789012 -AdSecurityInheritance "All" .EXAMPLE $Splat = @{ Id = "SG_SiteAdmins_XXXX" LDAPPath = "OU=Users,OU=XXXX,OU=Sites,DC=EguibarIT,DC=local" AdRight = "CreateChild,DeleteChild" AccessControlType = "Allow" ObjectType = '12345678-abcd-1234-abcd-0123456789012' AdSecurityInheritance = "All" ObjectType = '12345678-abcd-1234-abcd-0123456789012' } Set-AclConstructor6 @Splat .EXAMPLE $group = Get-AdGroup "SG_SiteAdmins_XXXX" $Splat = @{ Id = $group LDAPPath = "OU=Users,OU=XXXX,OU=Sites,DC=EguibarIT,DC=local" AdRight = "CreateChild,DeleteChild" AccessControlType = "Allow" ObjectType = '12345678-abcd-1234-abcd-0123456789012' AdSecurityInheritance = "All" ObjectType = '12345678-abcd-1234-abcd-0123456789012' } Set-AclConstructor6 @Splat .NOTES Used Functions: Name | Module ---------------------------------------|-------------------------- Get-ADObject | ActiveDirectory Get-Acl | Microsoft.Powershell.Security Set-Acl | Microsoft.Powershell.Security New-Object | Microsoft.Powershell.Utility Get-AdObjectType | EguibarIT.DelegationPS Test-IsValidDN | EguibarIT.DelegationPS Get-CurrentErrorToDisplay | EguibarIT.DelegationPS .NOTES Version: 2.0 DateModified: 09/Feb/2024 LasModifiedBy: Vicente Rodriguez Eguibar vicente@eguibar.com Eguibar Information Technology S.L. http://www.eguibarit.com #> [CmdletBinding(SupportsShouldProcess = $true, ConfirmImpact = 'Low')] [OutputType([void])] param ( # PARAM1 STRING for the Delegated Identity # An IdentityReference object that identifies the trustee of the access rule.
