With this authentication method, user authentication is delegated to Windows NT domain controllers.

Spotfire Server must be installed on a computer running Windows and there must be a working Windows NT 4 Server domain controller or a Windows Server 2000 or later domain controller running in mixed mode. This is a legacy solution that should only be used if LDAP cannot be used.

The Windows NT Domain authentication method can be combined with a user directory in either Windows NT Domain mode or in Spotfire database mode.

When combining this authentication method with a Spotfire database user directory mode, the post-authentication filter must be configured for auto-creating mode, so that the users will be automatically added to the user directory. When combining it with a Windows NT Domain User Directory, the default blocking post-authentication filter is already correctly configured.
