Re: LDAPI support in JLDAP

[Endi Sukma Dewata <edewata@redhat.com>]

Hi Marc,

Thanks for your suggestions. I tried to create a subclass of
LDAPConnection but I was getting a lot of problems accessing
non-public methos/classes belonging to com.novell.java package.
But it gave me a different idea, I finally got it to work
using a custom socket factory.

First I create an LDAPIUrl to parse LDAPI URL:

  LDAPIUrl url = new LDAPIUrl("ldapi://%2ftmp%2ftest");

Then I create a LDAPISocketFactory and pass it to LDAPConnection:

  LDAPISocketFactory factory = new LDAPISocketFactory();
  LDAPConnection connection = new LDAPConnection(factory);

To establish the connection I use the hostname parameter of the
connect() function to pass the LDAPI path:

  connection.connect(url.getPath(), 0);

The socket factory will use the path to create the Unix domain
socket and ignore the port:

  public Socket createSocket(String path, int port) {

      AFUNIXSocket socket = AFUNIXSocket.newInstance();
      socket.connect(new AFUNIXSocketAddress(new File(path)));

      return socket;
  }

So thanks a lot and never mind about the proposal. :)
