If the ExternalAuthCreatesUsers flag in the sync.conf.default file is missing or is set to ON/TRUE, valid NT Domain users can log in or synchronize and have their accounts automatically created.

If this flag is set to OFF/FALSE, user and group accounts are not automatically created. In this case, run the AGDomainSync tool to import the users that you want to use M-Business Server.
