Update Authentication

For Niagara 4 platforms, this Platform Administration view is available on Windows-based hosts only. You use it to specify the Windows users group for platform administrator access.

The authentication in Niagara 4 uses only basic (native Windows OS user) authentication for platform access—file/digest platform access is no longer an option. Nor is there a platform User Manager view Instead, you must use native Windows tools to create and manage Windows OS users and groups.

This theme also applies to the TCP/IP Configuration view for the Niagara 4 Windows host, which is available, but is read-only (allowing you to review current TCP/IP settings). Also, there is only one level of platform access for any Niagara 4 host—admin level. This level applies to Windows platforms as well as to controller platforms.

When you click Update Authentication on a Windows host, you see a login window, as below.

Use your standard Windows login credentials—if the host is on a Windows domain, log in using the credentials you use when logging in to that domain. This is necessary to limit the number of possible domain groups to only those groups in which you are a member. Such groups are selectable in the next window to chose the sole Windows users group for platform daemon access, as shown in the figure below.

This window lets you select the one Windows users group that can make platform connections to this host. Groups include Windows built-in user groups (include “BUILTIN” or “NT AUTHORITY” prefix), as well as any locally-defined user groups. If the host has been added to a Windows domain, groups defined in that domain are also listed and available.

NOTE: Domain groups are limited to only those in which the login user is a member.

When platform-connected to the Niagara 4 Windows host, some Platform Administration view buttons are unavailable, as shown in the figure below.

As shown above, Change Date/Time, Commissioning, and Reboot are unavailable when the platform is connected to any Niagara 4 Windows host (remote or local). For a local platform connection, Configure Runtime Profiles is also unavailable.
