Answer 1

Web sockets is a specific protocol, like HTTP, and it has "nothing" to do with a TCP/UPD socket.
You cannot connect with web-sockets to an LDAP-server, let alone connect to a different domain without receiving the appropriate CORS http-headers (and the browser supporting CORS).

You need to write a proxy WebSocket server application so that you can communicate with the LDAP-directory. You cannot do it in JavaScript (unless you want to use an ActiveX object, which will be incompatible with non-Microsoft browsers (and newer Microsoft browsers).

You better do it with plain-old AJAX with an asynchronous handler.
You don't need WebSockets for that, you're only wasting bandwidth.
