Testing domain AD credential with PowerShell one liner

This is a one liner command script to connect to Active Directory and verify user name and password credentials provided. I am using  System.DirectoryServices.DirectoryEntry .net object here to connect to LDAP server (In my case it is Active Directory). When you are connected successful with correct information you get DistinguishedName and Path information of Active directory in return.

New-Object System.DirectoryServices.DirectoryEntry('LDAP://DC=vcloud-lab,DC=com', 'domain\username', 'password')

If provided Ad credentials are not valid you will see error 'The username or password is incorrect.'
