Get an AD Object without RSAT and fast

In this article we’ll see the function I’ve built to get an AD Object without RSAT and fast. I’ve been thinking for a while to write a new function, mainly because I wanted to pass multiple SamAccountNames without having to write a filter. However I recently had to go through a ton of users and fast, this is when I though that I could finally write my custom function, which leverages┬áSystem.DirectoryServices.DirectorySearcher, so it doesn’t even require RSAT.

There are a lot of guides are out there how to use it, this article is meant to share with you the function I built around that.

The things I like the most about this:

  • It’s fast. The more objects you’re querying, the faster it’ll be compared to Get-ADObject/Get-ADUsers/Get-ADGroup.
  • You can use it to query any kind of Object.
  • You can pass multiple SamAccountNames (Sam1, Sam2, SamN), SIDs or DistinguishedNames.
    • You can also choose to pass a partial parameter with a wildcard, for example: MyUserSam*
  • You can also choose to write a plain LDAP Query instead of the SAM/SID/DN.
  • Filter down for an account status with -AccountStatus. By default you’ll get both Enabled and Disabled.

Other features:

  • You can still specify whatever Properties you need, including * for all of them.
  • You can choose to display the LDAP filter the function has used to query AD.
  • You can also choose to translate the SID. Unfortunately what you get back it’s not a string but a byte array.
  • You can specify an objectCategory with -ObjectCategory without having to use a custom ldap filter.
  • Also, you can confine the search to a specific OU (SearchRoot), use a specific Server and Port.

Here’s the code ­čÖé
