MITMf/core/protocols/ldap/LDAPServer.py
byt3bl33d3r 9712eed4a3 This is 1/2 of the work done... lot's of cool stuff!
I've re-written a decent amount of the framework to support dynamic config file updates, revamped the ARP Spoofing 'engine' and changed the way MITMf integrates Responder and Netcreds.

- Net-creds is now started by default and no longer a plugin.. It's all about getting those creds after all.
- Integrated the Subterfuge Framework's ARPWatch script, it will enable itself when spoofing the whole subnet (also squashed bugs in the original ARP spoofing code)
- The spoof plugin now supports specifying a range of targets (e.g. --target 10.10.10.1-15) and multiple targets (e.g. --target 10.10.10.1,10.10.10.2)
- An SMB Server is now started by default, MITMf now uses Impacket's SMBserver as supposed to the one built into Responder, mainly for 2 reasons:
  1) Impacket is moving towards SMB2 support and is actively developed
  2) Impacket's SMB server is fully functional as supposed to Responder's (will be adding a section for it in the config file)
  3) Responder's SMB server was unrealiable when used through MITMf (After spending a day trying to figure out why, I just gave up and yanked it out)

- Responder's code has been broken down into single importable classes (way easier to manage and read, ugh!)
- Started adding dynamic config support to Responder's code and changed the logging messages to be a bit more readable.
- POST data captured through the proxy will now only be logged and printed to STDOUT when it's decodable to UTF-8 (this prevents logging encrypted data which is no use)
- Responder and the Beefapi script are no longer submodules (they seem to be a pain to package, so i removed them to help a brother out)
- Some plugins are missing because I'm currently re-writing them, will be added later
- Main plugin class now inharates from the ConfigWatcher class, this way plugins will support dynamic configs natively! \o/
