You say "Out of the box, Fedora 18 will be able to join a Windows Active Directory.(...) I would like to think other distributions would pick up on this, but major kudos to Fedora for finally having the smarts to make this a reality for users"

You should really thank Samba devs at Samba.org for this, it??s they who added this feature to Samba, and Fedora devs only choose to package Samba 4.0 w F18....

Sheesh....
