Custom Intellisense for AD cmdlets with SearchBase parameter

Sup’ PSHomies!

You gotta love the PowerShell community! Found this little gem in my twitter feed (again) :-). Trevor Sullivan demonstrates how we can create custom intellisense for cmdlets if they haven’t been provided as yet. Great video! Trevor really does a great job explaining this.

The first thing that came to mind was Active Directory! I can’t tell you how often I needed the DistinguishedName of an OU. Now imagine having a dynamic list generated for you! No more errors,  just select and you’re good to go! Excited??? I sure am!

Sometimes you need to limit your searchbase depending on you AD size. Let’s say I want to retrieve all users starting from a specific point

Get-ADUser -Filter * -SearchBase 'OU=Users,OU=IT,DC=pshirwin,DC=local'

A simple typo will generate an error. Distinguished names are notorious for being lengthy…

Now the obvious AD cmdlets would be Get-ADUser,Get-ADGroup & Get-ADComputer. So that got me thinking , just how many AD cmdlets have SearchBase as a parameter?

Get-Command -Module ActiveDirectory |
ForEach-Object{
   $psItem.Name |
   Where-Object {
        (Get-Command $psItem).ParameterSets.Parameters.Name -eq 'SearchBase'
   }
}

Turns out there are quite a few using SearchBase

  • Get-ADComputer
  • Get-ADFineGrainedPasswordPolicy
  • Get-ADGroup
  • Get-ADObject
  • Get-ADOptionalFeature
  • Get-ADOrganizationalUnit
  • Get-ADServiceAccount
  • Get-ADUser
  • Search-ADAccount

So I can have Intellisense on all these cmdlets? Awesome!!!

Intellisense completed the DistinguisedName on -SearchBase for me. No need to type it in, no errors, just select and go!

TabExpansionSearchBase

Here’s the result:

TabExpansionSearchBase-result

I’m sure you guys will find your own use for this… Thanks again Trevor for bring this to our attention! Good looking out for the community! Be sure to watch Trevor’s video for in depth explanation.

Hope it’s worth something to you…

Ttyl,
