Has anyone got their Linux systems authenticating against Active Directory without using Likewise Open?

We are close to implementing Likewise Open, but first we need to rename roughly 70 of 110 Linux servers so that their hostnames are not longer than 15 characters. This is required because Likewise Open actually joins the Linux computer to the domain, and it fails to do so if the hostname is too long due to some legacy NetBIOS naming limitation.

Is there a way to authenticate via AD, using only LDAP perhaps?
What are the advantages/disadvantages over doing it like that vs just using Likewise?
