I am trying to figure out how to authenticate users against my SME domain using CentOS as a workstation. I have several WinXP machines running off of the SME domain no problem but I cannot figure out what authentication method/settings to use with the CentOS box. It should be easy right?

What I meant to say is, what is the best authentication method to use for Linux workstations, and what settings do I need to use for that method?
