Serv-U FTP Server 8.0 Windows Authentication Changes

It appears that there is a change in the new version of Serv-U FTP Server that affects Windows Authentication. This change is that the Windows AD user must be a member of the "Domain Users" AD Group or Serv-U FTP Server will give you an Access Denied error upon connection. In the past you just needed an AD User account and could assign it to a "No Permissions" group so that it could only be used for FTP, however that is no longer the case.
