Test if AD object/path exists

This Test-QADObject (Test-QADPath) function I have created gives a quick true or false answer on whether a specific user, computer, group, OU already exists in your domain.

Test-QADObject 'OU=demo,DC=quest,DC=local'

Test-QADPath k*

I have posted the whole code with proper help and parameter handling to poshcode. Here’s a simplified one for the blog:

function Test-QADObject {
 (Get-QADObject $Identity -DontUseDefaultIncludedProperties `
  -WarningAction SilentlyContinue -ErrorAction SilentlyContinue `
  -SizeLimit 1) -ne $null

    How can I use this function to help with the issue I’m working on? I posted this Q? on PowerGui.org

    I am trying to use this snippet and running into issues. I am trying to test that OU’s, Access Templates, and Access Template Links all exist before running the script to onboard a new site ou structure. Using Test-QADObject to verify the Access Templates works great, both if they exist (returns True…) and if they don’t exist (returns False…). However, OU’s are not working. If an OU exists, it returns True, but if not, it errors out:

    Get-QADObject : Administration Service encountered an error when retrieving properties of the object
    Directory object not found. (Exception from HRESULT: 0x8007208D)

    At E:\Quest_Software_Project_Files\Scripts\OnboardNewSite\Test-Path.ps1:107 char:16
    + (Get-QADObject <<<< $Identity -DontUseDefaultIncludedProperties -WarningAction SilentlyContinue –
    ErrorAction SilentlyContinue -SizeLimit 1) -ne $null
    + CategoryInfo : NotSpecified: (:) [Get-QADObject], COMException
    + FullyQualifiedErrorId : System.Runtime.InteropServices.COMException,Quest.ActiveRoles.ArsPower

      I think you are getting the exception because you have non-existent domain com.corp.net.

      Do you really need to test for that? Or just whether OU in the domain exists? In my experiments, if the domain is right – script works for OUs just fine.
