• Step by Step Installation and Configuration of OpenLDAP as Proxy to Active Directory | haroonferoze – This guide describes how to install and configure OpenLDAP as proxy to Active Directory.
• Integrate Active Directory and OpenLDAP | Networking content from Windows IT Pro – OpenLDAP’s proxy service can allow LDAP operations to cross the boundaries between AD and OpenLDAP deployments. To demonstrate this proxy service, we walk through the steps to make AD’s cn=Users container, which by default contains all user objects, part of an OpenLDAP directory. To produce the examples in this article, I used CentOS 4.3, OpenLDAP 2.2.13, and AD running on Windows Server 2003 R2. Later in the article, I’ll show you a limitation in the commonly deployed OpenLDAP 2.2, which you can solve by installing OpenLDAP 2.3 on CentOS 4.3.
• Let’s Chat — Self-hosted chat for small teams – WHAT IS THIS THING? Some backstory. Way back in 2012, we didn't like any of the existing chat services out there. So we decided to write our own. Let's Chat is a persistent messaging application that runs on Node.js and MongoDB. It's designed to be easily deployable and fits well with small, intimate teams. It's free (MIT licensed) and ships with killer features such as LDAP/Kerberos authentication, a REST-like API and XMPP support. Let's Chat is a side-project of the development team at Security Compass. (A real life 10% time project!)
