After the Windows workstation has joined the DSfW domain and the computer has been restarted (as explained in Section 13.1, Joining a Windows Workstation to a DSfW Domain), DSfW user accounts can be used to log on to the Windows workstation.
Start the Windows workstation or press Ctrl+Alt+Del to bring up the Windows log on dialog box.
In the Log On to Windows dialog box, enter the user name and password of a user that has been provisioned for DSfW. Initially, the only provisioned user is the Administrator account created when you installed DSfW.
In the Log on to field, click the down-arrow to select the DSfW domain (identified by its NetBIOS name), then click OK.
