This week I stumbled upon this presentation done by Pieter Baele, about the integration of Linux, Microsoft AD and OpenDJ, to build a secure efficient naming and security enterprise service.
The presentation covers the different solutions to provide integrated authentication and naming services for Linux and Windows, and described more in depth one built with OpenDJ. Overall, it has very good information for the system administrators that need to address this kind of integration between the Linux and the Windows world.
