Windows Domain logon
If your users are logged on to a Windows domain, this option (available with the configuration server-based model in the Deployment Wizard) automatically logs users on to Host On-Demand using their Windows user name. The Host On-Demand logon window does not appear and the Windows user name is used as the Host On-Demand user ID. If a Host On-Demand user ID does not already exist (matching the Windows user name), you can also choose to have a user ID automatically created in the specified Host On-Demand group.
See Logon Type for more information about choosing how users access the Host On-Demand configuration server.
