Check user exist in AD with powershell

[avanis]

I have a condition to check if user exist in AD so that while rehiring we do not create a new userid for the same user who has a deactivated account and reactivate the same account.

I found ways to to do that via AD activities but that uses LDAP.

I do not have LDAP and want to do the same via powershell script.

Can anyone help how to do that.

I think as a pre-requisite you need to have RSAT Installed on a machine from where you would like to query AD.

We have it but i need powershell script and not use ad activities.

Here is an example:

Import-Module Activedirectory

$newusers = @("john.snow","ned.stark01","tyron.lannister")

foreach ($newuser in $newusers)

{

if (Get-aduser $newuser)

    {

    write-host "$newuser already exists"

    }

else

    {

    New-aduser -samaccountname $newuser

    }

}
