Test-LDAPS.ps1

<#
.SYNOPSIS
This cmdlet is used to verify your domain controller is correctly configured to accept LDAP over SSL connections


.PARAMETER ComputerName
Specifies one computer name or a comma-separated array of computer names. This cmdlet accepts
ComputerName objects from the pipeline or variables.

Type the NetBIOS name, an IP address, or a fully qualified domain name of a remote computer. To specify the
local computer, type the computer name, a dot `.`, or localhost.

This parameter doesn't rely on PowerShell remoting. You can use the ComputerName parameter even if your
computer isn't configured to run remote commands.
