So I’ve spent some time for something at work figuring out how to get an Ubuntu server to authenticate users with a Windows 2003 Server Active Directory. Using the process I’ve found by combining various sources, my instructions show how to get a machine setup such that users logging in to the shell, accessing a samba share and checking out a website (or sub-directory of one) can all be authenticated using credentials centrally stored in a separate Active Directory server.

Check out my articles I’ve posted here:
