This is a repost from here: http://serverfault.com/questions/380590/sharepoint-2010-not-seeing-active-directory-users Not sure how to migrate questions.
I'm pretty new to Active Directory and SharePoint but I was given to understand they are supposed to play well together.
Now I have successfully set up AD with multiple user accounts that work on any member computer. I have also successfully installed SharePoint 2010 Server on an AD machine. Both the AD server and SharePoint servers are on separate machines (VMs running on ESXi to be precise).
I can only log on with user accounts I create on the local server. Furthermore the user browser thing for adding users will only see local users.
I've followed the advice here http://technet.microsoft.com/en-us/library/cc262350.aspx#section2 for Classic authentication and also NTLM claims based authentication but to no avail.
Is there something fundamental I am getting wrong here? I'd be really thankful for any help you can lend me; I've been googling and scratching my head for a couple of days now.
