when use dsquery tool, can select localhost:5432 target using ds tools can information want

but when try use powershell commands -server;localhost:5432 got error:

using get-adobject ou get-aduser

ps c:\users\administrator> get-adobject -server localhost:5432 -filter 'objectclass -eq "user"'

powershell cmdlets dont "speak pure ldap", communicate ad web services (and maybe encrypted). service runs on dc when can run posh command against (... -server <domain controller> ).
adws uses special port, neither ldap nor gc. dont know whether can tell adws use snapshot. i'd think no.

but work: connect snapshot using [adsi] , [adsidearcher] or corresponding .net classes. these classes can connect non-ad-ldap server.

$direntry = new-object system.directoryservices.directoryentry( "ldap://mydc.contoso.com:5432/dc=contoso,dc=com" )

see http://blogs.technet.com/b/heyscriptingguy/archive/2010/08/23/use-the-directorysearcher-net-class-and-powershell-to-search-active-directory.aspx  or google around [adsi].
