Integrating OpenDS and Samba as a Primary Domain Controler...
By Ludo on Jun 12, 2009
A few weeks ago, I was exchanging emails with one of the members of our community who was having issues with adding Samba related schema to OpenDS. The exchange turned into a few issues raised against OpenDS and a couple of builds later, he happily reported having all his problems solved and having a fully functional Primary Domain Controler running on his Ubuntu machine. And he immediately posted a detailed How To Guide on the OpenDS wiki.
I haven't tried to reproduce the settings, but if you need to run Samba with LDAP on your server, you might want to check OpenDS and follow the steps to get it running.
