Can Active Directory on Windows Server 2003 or 2008 scale to support millions of users for a SharePoint 2010 implementation? Not total objects but total users so there would be additional group objects, etc. Can SharePoint 2010 support this many users as well?<br />
<br />
If the answer to both questions is yes are there any implications, gotchas or issues concerning the support of this large a user base both within AD and SharePoint?<br />
<br />
Thanks in advance!
