Connect To LDAP Via Proxy

[Murali Klugman]

I currently have the following code to connect to a directory server. I have been told that I need to have the code go through a proxy server (specifically a Squid proxy, if that's relevant). I can't figure out what to change or add in this code to get it to route through the proxy. Any/ all thoughts are welcome.

String url = "ldap://" + IP + ":" + Port;
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, url);
env.put(Context.SECURITY_AUTHENTICATION, "none");
env.put(Context.SECURITY_PRINCIPAL, UserID);
env.put(Context.SECURITY_CREDENTIALS, Password);
InitialLdapContext ilc = new InitialLdapContext(env,null);

Thank you
