[Twisted-Python] How work ldaptor and twisted

[Julien Peeters]

I read all these but I don't understand how do I have to use the
deferred return by the connect method from the LDAPClient

c = ldapconnector.LDAPClientCreator(reactor, pureldap.LDAPClient)
d = c.connect('...')

I don't understand why I have to add all my callback's to this deferred.
If I understand the meaning of a deferred, it represent a result that
will be return. And then, once connected, the deferred have no sense
anymore for me...

For example this code:
	def fun(proto):
		d = proto.send(request)
		d.addCallback(responseHandler)
		return d

I don't understand why I have to return the deferred and how it interact
with something else.

Globally, I understand what is the reactor, what is a deferred, how can
I make a client, a server. My problem state in the interaction of these
concepts. The link between them from a technical and implementational
point of view.

There is some detailed sequence diagrams some where I can found?

I suppose I miss an important part of the concepts, but I don't know
what.

Julien.
