On previous ubuntu release, to get connected to Active Directory need a lot of work to do. But in Hardy release, all this step has been simple as a new package name "likewise-open" is being uploaded into Hardy's repository. Likewine Open is an application to make Linux to Active Directory easier to setup. Only a few clicks needed in order to make your linux ubuntu to get connected to Active Directory.
Likewise Open enables Linux, Unix and Mac authentication on a Microsoft network using Active Directory. A user can now interactively log in to the Linux, Unix or Mac machine using Active Directory credentials, and can access any kerberized services that the non-Windows machine hosts.I was really pleased with the action taken by ubuntu to include this package into official repository as this is an important application being used by a lot of ubuntu user in order to access Active Directory which previously need to be setup my intermediate linux user.
