Get single LDAP object

function Get-LDAPObject {
param([string[]]$LDAPPath)

begin {
}

process {
if ($_)
{
if ($_ -is [string])
{
new-object system.directoryservices.directoryEntry($_)
}
else
{ throw "Pipeline input must be [string]."
}
}
}

end {
if ($LDAPPath) {
foreach ($Path in $LDAPPath) {
new-object system.directoryservices.directoryEntry($Path)
}
}
}
}

Get content of an LDAP container

function Get-LDAPChildren {
param([string[]]$LDAPPath)

begin {

function getContainer([string] $path)
{
$con = new-object system.directoryservices.directoryEntry($path)
$con.PSBase.Children
}
}

process {
if ($_)
{
if ($_ -is [string])
{
getContainer($_)
}
elseif ($_ -is [System.DirectoryServices.DirectoryEntry])
{
getContainer($_.PSBase.Path)
}
else
{ throw "Pipeline input must be [string] or [System.DirectoryServices.DirectoryEntry]."
}
}
}

end {
if ($LDAPPath) {
foreach ($Path in $LDAPPath) {
getContainer($Path)
}
}
}
}

Remove an object from an LDAP container

function Remove-LDAPObject {
param([string[]]$LDAPPath)

begin {

function remove([string] $path)
{

if ([system.directoryservices.directoryEntry]::Exists($path))
{
$obj = new-object system.directoryservices.directoryEntry($path)
$obj.PSBase.DeleteTree()
$obj
}
else
{
throw "Object does not exists!"
}
}
}

process {
if ($_)
{
if ($_ -is [string])
{
remove($_)
}
elseif ($_ -is [System.DirectoryServices.DirectoryEntry])
{
remove($_.PSBase.Path)
}
else
{ throw "Pipeline input must be [string] or [System.DirectoryServices.DirectoryEntry]."
}
}
}

end {
if ($LDAPPath) {
foreach ($Path in $LDAPPath) {
remove($Path)
}

}
}

Add an new object to an LDAP container

function Add-LDAPObject {
param([string]$Container, [string]$Class, [string]$RDN)

begin { }

process { }


end {
if ($Container -and $Class -and $RDN) {


if ([system.directoryservices.directoryEntry]::Exists($Container))
{

Write-Warning "Adding Object $RDN of type $Class to $Container"

$obj = new-object system.directoryservices.directoryEntry($Container)
$newobj = $obj.PSBase.Children.Add([string]$RDN,[string]$Class)
$newobj.PSBase.CommitChanges()
}
else
{
throw "Container does not exists!"
}
}
}
}

Define alias for function

Set-Alias LDP Get-LDAPObject
Set-Alias LDC Get-LDAPObject
Set-Alias RLDP RemoveLDAPObject
Set-Alias ALDP Add-LDAPObject
