Net::LDAP is written completely in Ruby with no external dependencies. It supports most LDAP client features and a subset of server features as well. Net::LDAP has been tested against modern popular LDAP servers including OpenLDAP and Active Directory. The current release is mostly compliant with earlier versions of the IETF LDAP RFCs (2251-2256, 2829-2830, 3377, and 3771). Our roadmap for Net::LDAP 1.0 is to gain full <em>client</em> compliance with the most recent LDAP RFCs (4510-4519, plutions of 4520-4532).

The simulator and RubyMotion REPL make on-device testing a painful cycle of code, compile, check, repeat. *Especially* when it comes to testing the UI, where inexplicable differences can crop up between a device and the simulator. Motion-Xray is an in-app developer's toolbox. Activate Xray (usually by shaking the phone) and a UI editor appears where you can add, modify, and remove views. Why stop there! There's a log panel, and an accessibility panel that gives you a visiualization of how you app "looks" to the blind or color blind. And you're damn right it's extensible! You can write new UI editors, register custom views, and add new panels, for instance maybe you need a Bluetooth device scanner, or a way to check API requests. Enjoy!
