Note Submitter: ugo dot martins at gmail dot com ---- Hello everyone, I want to use Ldap in one of my aplication, but my question is: How can we know what user, is logged in windows, with the aplication in a server. So what I want to know is how can I know a name of a client user. I had search in many sites, but neither tell me this. Thks for your support, from Portugal, Hugo Martins
