ProcessOU

From Terminal23wiki

Call ProcessOU with an OU string that looks like a location such as "Security Groups/Resource Groups/File Server." ProcessOU will then use TestIfOUExists, and if it doesn't, will use CreateADOU. In this way, if you have an AD user or object you need created in a particular location, before creating it, just call ProcessOU with the target location. This will either verify or create it.

function CreateADOU ($strOULocation,$strNewOU)
{
   $strLDAP = "LDAP://" + $strOULocation + "dc=SUBDOMAIN,dc=DOMAIN,dc=com"
   $objOU = [ADSI]$strLDAP
   $objNewOU = $objOU.Create("organizationalUnit", "ou=$strNewOU")
   $objNewOU.SetInfo()
}

function TestIfOUExists ($strOUstring)
{
   $strLDAP = "LDAP://" + $strOUstring + "dc=SUBDOMAIN,dc=DOMAIN,dc=com"
   $objTest = [ADSI]$strLDAP
   if ($objTest.Name -ne $null){ return $true } else { return $false }
}

function ProcessOU ($strOUInput)
{
   $strLocation = $strOUInput.split("/")
   $strOUPreTest = ""
   $strOUPostTest = ""
   foreach ($i in $strLocation)
      {
         $strOUPreTest = "ou=" + $i + "," + $strOUPreTest
         if (TestIfOUExists $strOUPreTest -eq $true)
            { }
         else 
            { CreateADOU $strOUPostTest $i }
         $strOUPostTest = $strOUPreTest
      }
}
