Since a lot of us has been coming from Zentyal, why not a DC compatible with Active Directory/GPO (Windows Server replacement ) which can handle Linux clients as well (maybe Desktop wallpapers, shortcut items, etc).
Did I say I came from Windows (it should be somewhere in my intro)?
Because at the moment to have samba4 for AD and openchange to substitute Exchange you must delete all other pachages and so you have a zentyal clone…just because of samba4 internal ldap that is not compatible with openldap
Samba4 would be a very good contribute to the project because it would give SME the possibility to replace a lot of windows servers and keep the possibility to push gpo’s to the clients. This makes the trancission easier to nethserver.
