ControlPoint counts all individual users who currently have permissions in SharePoint, either directly, through an Active Directory group, and/or through a SharePoint group.
Excluded from this user count are:
·external or anonymous users
·most built-in Active Directory accounts
NOTE: ControlPoint will consider the account NT Authority\authenticated users and the Active Directory group Everyone to encompass all active Active Directory users (that is, for these groups, Disabled users will not be counted). If either of these accounts has permissions within the SharePoint farm, it will be reflected in the user count.
TIP: If you suspect that there are disabled or deleted Active Directory user accounts that still have permissions in SharePoint, either explicitly or through a group other than NT Authority/authenticated users or Everyone, generate an Orphaned Domain Users report and delete them from SharePoint so they will not be included in the user count.
Note that you can calculate the latest user count from the License Info dialog.
