Single Connect supports Domain Authentication by including Single Connect and the user’s PC in the Domain. Once this is in place, the** Windows Authentication** option will be ready to use.

The username must be defined as a user in Single Connect, and realms must be created for connection and policy enforcement by a system admin.
