Only users that have visited the site collection are displaying

Mar 22, 2012 at 3:43 AM

I have a new SharePoint 2010 site/server that we have not released to production yet. We have about 400 user profiles that are being synched from Active Directory and when I choose the "User Profile" option from the "Choice type of collection" under Pivot Viewer Collection Configuration, the only users that are displayed in the Pivot Viewer appear to be the users that have visited the site. Any ideas if this is normal or what I might be doing wrong? Another question while I am at it...is it possible to filter our certain users like the domin service accounts (that we use for SharePoint)? I don't really want the site visitors to see these accounts.

Thanks!
