Net::LDAP for Ruby (also called net-ldap) implements client access for the Lightweight Directory Access Protocol (LDAP), an IETF standard protocol for accessing distributed directory services. 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).

Treequel is an LDAP toolkit for Ruby. It is intended to allow quick, easy access to LDAP directories in a manner consistent with LDAP's hierarchical, free-form nature. It's inspired by and modeled after [Sequel][sequel], a kick-ass database library. For more information on how to use it, check out the [manual](manual/index_md.html).

'Ruby/ActiveLdap' is a ruby extension library which provides a clean objected oriented interface to the Ruby/LDAP library. It was inspired by ActiveRecord. This is not nearly as clean or as flexible as ActiveRecord, but it is still trivial to define new objects and manipulate them with minimal difficulty.
