[CentOS] Ad integration with centos 6

Can anyone point me to a tutorial on using Active Directory to authenticate
a centos 6 server? I just want to use it to authenticate, ssh and restrict
access to a particular ad group. I prefer to use the lightest method
possible. I know you can use ldap, or winbind, etc. I have been trying to
follow the ones I have been googling, but none of them seem "quit complete.
My issue is that I have no ldap experience.
