samba - Oct 2013 - Instruction how to Connect a Linux computer to Active Directory

Hi,

I am new to Linux, and I am trying to join a CentOS 6.4 computer to Windows
Active Directory Domain. I have read an follow documentation that I have
found online but I have not been able to successfully join the Linux
computer to the AD. I am getting overwhelmed by the bast amount of
information that is available but a lot of that is not accurate or simple
doesn't apply to what I am trying to do. Can you please point me to where I
can get reliable and up to date information on how to do the task that I am
working. Thank you any help will be very appreciated.
